- used TEXTCOLOR_ #defines for colorizing CCMD list, remove use of strbin1.
- Fixed: crash when closing ZDoom in the save menu and a memory leak.
Merge branch 'maint'
- fixed: ChangeSpy didn't check if a player's camera's player pointer was valid before using it to get an index into the players table.
- commented out autoloading of .DEH lumps for maint branch.
- changed autoloading of *.deh lumps: it is now controlled by a CVAR with 3 options: never load *.deh lumps, load all of them or only load the last one. *.deh loading is disabled by default.
- Use a more conformant C++ preprocessor macro identifier for Unix systems.

The 'unix' identifier isn't defined when '-std' is passed to the compiler (tested with gcc and clang), so use '__unix__' which is well enough documented.
- added separate colors for the various types of 2-sided walls for the overlay automap. They previously all mapped to the same CVAR.
