[Gchempaint-main] GChemPaint 0.4.1 released

[Jean Bréfort]

Hi,

This is a minor bugs fix release. Here are the main points:

- Some minor bugs fixed. 
- Removed GTK_DISABLE_DEPRECTATED and similar tags to avoid problems
with gtk+-2.4 and gnome-2.6. 
- Needs OpenBabel-1.100.2.

Best regards,

Jean
