Today's progress; half working, but i better commit to prevent
conflicts tomorrow :)
- added storage for regions in spacedata
- added space switching (unfinished, gives mem-free errors)
- bugfix: icon of timewindow gave error on split-area
- cleaned interface_icons.c a bit, no warnings
- first work on space new() callbacks, they have to make regions too
NOTE: probably files saved with 2.5 crash now. Have to look at
patching this.
NOTE2: the Makefiles required libeditor screen twice... scons too?
