Update BUILDING.txt for latest version.
cleanup and checks to avoid bad addresses

- removed obsolete name reads

#73 bad addresses:
- commented out unused prefix stuff in words
- checks for invalid materials before attempting to read
-
Use process_vm_{read,write}v instead of ptrace

This approximately doubles the speed of Dwarf Therapist on Linux, and
fixes #73.
Silence bad address errors.
Remove OS-specific entries from .gitignore.

.gitignore should only store items that are generated by the code in the
repository. If your operating systems generates temporary files, put
those in your .gitignore_global.
Mv etc -> share, use applicationDirPath (fixes #30)

Also build outside of bin.
Add DATADIR, search_paths for game_data.ini
