This removes all encoding issues from passing on a script to cmd.exe on
Windows, as it now uses proper wide character API there.

Not much changes on other OSes, but we don't create temporary scripts
anymore.

Try and use Unicode variants of the Windows process creation API in
order to support filenames (and possibly environment) outside the
locale codepage.

WARNING: Implications on using Unicode environment are unknown.
It might affect the called process, or not, not sure.

Instead of fiddling with the "chcp" command in the generated batch
script on Windows, convert the whole script content into the system
codepage before executing it.

The working directory is passed in in UTF-8 encoding but Windows API expects
locale encoding here, so convert it.

Fixes #1076.

No behavioral changes.

Closes #1074.

Fix signals for GI

Combine the libraries from the GTK3 bundle with GTK from the GTK2 one
to get newer GLib & co for GTK2 builds.

If possible, register signals with the proper argument types (boxed or gobject).
This is required for successful introspection of the signals and important
for GI-based plugins.

As for the marshallers, if available use a predefined one from glib. Otherwise
use the generic marshaller available since 2.30 (in theory all signals could
use that one but it has a bit of overhead).

This builds on the gboxed conversions of earlier commits.

This also bumps the minimum glib requirement.
 - g_cclosure_marshal_generic requires 2.30 (if NULL is passed as marshaller
   to g_signal_new())
 - G_TYPE_KEYFILE requires 2.32

geany.desktop.in: Add Keywords field entry

Fix undo of line end type change

Simply call ui_update_statusbar() and ui_document_show_hide() like in
other undo actions.

At the moment undo of line end type change only undos the changes made
in the document but the different line ending settings remains active.

This patch fixes the issue by combining the line end scintilla undo action
with a new UNDO_EOL action responsible for updating the line ending
settings.

Fixes #409

Updated scintilla_changes.patch accordingly

geanyobject can be used by plugins to connect to plugin signals directly
(required for GI-based plugins). Access through GeanyData::object. The related
doxygen comments are @gironly for now, since plugin_signal_connect() is still
preferred.

Finally, the useless function pointer prototypes are removed from the
GeanyObjectClass structure as they became useless (they have been unused and
generally wrong since ever).

GeanyObject signals require GTypes to be gobject-introspection compatible.
