GtkDatabox Git

Changelog:
* Added:
- Convenience function to override the background-color of a databox:
gtk_databox_set_bg_color().
- Documentation in doc/html generated by ./configure --enable-gtk-doc
* Changed:
- Using libtool's versioning system, to avoid breaking binary compatibility
through every new minor-fixes release. Starting/resetting with 1:0:0 (see
'info libtool' on node Versioning::).
- Deprecated function gdk_cairo_create substituted with recommended code.
- Deprecated functions to get/set background substituted with recommended code.
- Deprecated function gtk_adjustment_changed removed conditionally,
for GTK+ version >= 3.18.0.
- Deprecated function gdk_cursor_new substituted with
gdk_cursor_new_for_display, in examples/all.c.
- Deprecated function gtk_widget_override_background_color substituted
with new function gtk_databox_set_bg_color, in examples/all.c
- Re-enabled deprecation warnings in Makefile.am.
- log2 macro for_MSC_VER made private and hidden from GtkDoc.
* Fixed:
- Autoreconf warnings: INCLUDES ==> AM_CPPFLAGS
- Seg-fault using deprecated macro G_TYPE_INSTANCE_GET_PRIVATE. Using
now all_get_instance_private() automatic functions.
- All remaining compiling warnings removed.
- examples/addremove wasn't working fine.
* Removed:
- libglade support, as it's based on GTK2.
* Updated:
- Distribution files: TODO, README, Doxygen.
- Minimum required versions for Pango and Cairo in configure.ac.
