There is no need to do it differently as Linux here, and it confuses the
autotools based compilation of geany-plugins which installs to libdir/geany
unconditionally.

Fix binary relocation support

Spawn fixes/improvements

As stated in spawn.c, "This module does not depend on Geany when
compiled for testing (-DSPAWN_TEST)."

On child_pid=NULL, the Windows process handle is now closed ASAP, so
no main glib event loop is required.

If there was two hashes (#) in an inline comment, only the content
between the two was considered a comment.

python: optimize skipEverything()

Most of the time there's no start of a string which means all the 10
strcmp()s are done for every character of the input. This is very expensive:
before this patch this function alone takes 55% of the parser time.
When comparing by character (and avoiding further comparison if the first
character doesn't match), this function takes only 11% of the parser time
so the performance of the parser nearly doubles.

In addition check for the "rb" prefix which is possible in Python 3.

Ported from universal-ctags.

Only fixed items can have keybindings but this manual entry was missed when one execute item was changed from fixed to optional.

Update Simplified Chinese translation

Also, as changing the color of the label button doesn't currently work
on GTK2, but would on GTK3 with this change, explicitly skip it for
consistency.

Closes #528.

French translation update

Apparently xgettext only recognize comments that are straight above the
translation, so move them where it can find them.

Update of Russian translation

Autodetect .bashrc, .bash_aliases, and the like

Show icons corresponding to MIME types in the file browser plugin

Remove a few unused Scintilla wrappers functions

GtkScrolledWindow in GTK 3.16 might have a minimum and natural height
of 0 if GTK_OVERLAY_SCROLLING is enabled (which is the default), so we
need to fix our overridden minimal height to never be greater than the
natural height.

Do that by only changing the minimal height if it is greater than what
we want.

I don't know why we didn't use to set 0 here, but it might be that a
height of 0 caused problems on older GTK versions, so keep 1 to be sure.

Autodetect /etc/bash_completion (and the like)

Splitted up autodetection patterns for Bash

This will match:

- `*.bash` (any manufactured Bash scripts)
- `~/.bashrc` (hidden Bash configuration in your home directory)
- `~/.bash_*` (partials included by bashrc, e.g. `.bash_aliases`,  `.bash_history`,  `.bash_logout`)
- `/etc/bash.bashrc` (global Bash configuration)
- `/etc/bash_completion` (and potentially any other `/etc/bash_*` file)

Add filetype configuration menu entries

This adds a "Filetype Configuration" under Tools->Configuration Files
with all filetype configuration files (grouped by language type).

This patch mostly reuses the stuff we already have in Geany - the menu
creation code from Document->Set Filetype, file creation in the .config
directory if it doesn't exist (similarly to filetypes.common) and config
file reloading when the file gets updated.

Don't resize message window when changing Geany's window height

Add linear tag remove path for cases where not many files are open
