2.5

The basics for InfoSpace.
Also added InfoSpace data to area by default, older files allowed to
have nothing here (space empty). (prevents reported crasher in switching
space info to others).

Also: added ifdeffed code in readfile.c to debug missing memory frees
from data read from files. (instead of "data from SCR" it will print
the actual struct names).
