The (almost) black color of the inside of the bottleneck is a bit too high
contrast and doesn't fit the rest of the icon (the only black part of it).
Use the "lamp yellow" as the base and lower the L in HSL representation of
the color so it just looks as darker lamp material.

After making the bottleneck wider (by shifting the curve to the left), the
curve became flatter which looks strange. Make the curve a bit more round
in the middle.

Implement Erlang ctags

... so the tags will appear in Geany.

Use consistent shadows across Geany

In principle, any scrolled window should have GTK_SHADOW_IN so the scrollbars
are not above the surface and there is a frame around the scrolled area.

The only exception are the elements of the main window where adding
GTK_SHADOW_IN causes there are too many shadows (or lines in 2D themes)
around the windows and the result isn't nice. So use GTK_SHADOW_NONE
for all main editor scrolled windows. (One additional exception is the
Help->Credits page which is gray and the extra frame doesn't look good.)

Replace frame around VTE with GtkViewport to avoid the extra line around.

Raise the second editor from the splitwindow plugin so it's at the same
level as the main editor.

Geany icon improvements

The 32x32 size can be created by downsampling the 48x48
icon by gtk at runtime but the result will be worse than
doing the same directly from the svg icon (48->32
conversion means downsampling by 1.5 which can introduce
some moire artifacts and loss of information). Since
32x32 are quite commonly used, it makes sense to ship
this icon size with Geany.

The png files have been optimized by pngoptim to remove
metadata and compress the icon better.

This way the non-highlighted part can still be shown.

The handle of the lamp icon looks strange. While
the image of the lamp itself is taken from top,
the handle looks it's taken from bottom.

Fix this by moving the wide part of the handle
down and moving the "shine" line to copy the
outer edge. Also adjust the handle curves a bit
to connect the lamp in a more natural way.

8ebac609 moved the makefile.win32,
so we need to use the new location.

The Light sublayer of the Lamp layer covers the lamp border
partly so it appears cut off. In addition, the Shine sublayer
doesn't follow the border properly. Adjust the curves in both
of these sublayers to fix the problem.

No visual change.

Using erlang.c from fishman/ctags.

For some reason we expect the plugins directly inside `$(libdir)` on
Windows instead of `$(libdir)/geany`, so install the plugins there on
Windows.

Enable new Scintlla lexer.cpp.verbatim.strings.allow.escapes lexer
property for ObjectiveC.

Also remove extra padding around the button's image to reduce its size
and try and avoid it expanding the tab's height.

This at least fixes the editor tabs height on Adwaita theme, where they
were 1px taller than normal.

Use the short name for EOL mode in the statusbar

Disable "rules hint" for the Documents tab

The "rules hint" property is used to tell the theme for which TreeView
even/odd rows should have a different color. This is typically used for
long rows or rows which need to be visually separated for some reason.

Currently the Documents sidebar view uses it which doesn't make much
sense because the row is short and neither of the other tabs in the sidebar
use it.

Merges PR #417.

This does not change anything in practice because static variables are
initialized implicitly as we need them anyway, but this makes things
clearer and more explicit.

Spell "Windows" as "Windows", not "Win".

Always use absolute path when opening projects from command-line

At the moment when geany project is loaded from commandline using
e.g. "geany myproject.geany", the relative path is used by geany
so e.g. Project->Recent Projects shows the relative path instead of
the absolute one (also if the project is already in the list with an absolute
path, additional entry with relative path is created).

Use main_get_argv_filename(), which is already used for ordinary files,
also for opening .geany files.

OS X integration

Create geany_run_script.sh in the temporary directory instead of the
working directory.

Fix compiler warning

The current implementation uses single menu for the toolbar and
menubar and reparents it when file menu is shown/hidden.
Connectiong "show"/"hide" signals doesn't work for menu items
on OS X (and I suppose Ubuntu either) so the template submenu is
never shown in the File menu.

The easiest fix seems to be having two identical menus the same
way we have them for recent files.
