graphics: basic terrain passibility
atlas: lots of changes to make atlas compile under linux
unix/X: more clipboard support - copy from 0AD to other programs
unix/debug: use sys_get_executable_name instead of hard-coded paths
... and lots of other misc. changes
This was SVN commit r4640.
Color: Moved SColor* structs into SColor.h, so they can be used without
indirectly including CVector[34]D.
Terrain: Added 'base colour', for the Actor Viewer to be able to
modulate the colour of normally-white terrain.
Removed some "using namespace std" (because it doesn't make the code
easier to read, and it defeats the point of namespaces, and the rest of
the code doesn't do it).
This was SVN commit r4392.
Territories: Fixed memory leaks.
Atlas: New section-toolbar. Fixed colour of brush grid. Moved open/save
into File menu. Added 3D-ish lighting control. Added 'busy'
notifications.
This was SVN commit r4079.
