Added files that are new from Flash.

I ran `git diff --ignore-space-at-eol --diff-filter=ACRTUXB
5d6ceae9b846aabb31b8ea4c51ce61ebac4a8f7f..master-newvegas-merge`, then
from the list of files that produced I removed those that I knew were
identical in the latest Bash code (eg. BAPI DLL), and those that had
since been deleted themselves. Also, fallout3.py and falloutnv.py are
not committed yet because they are unfinished.

The remaining files are ready to be dropped into Bash, except from those
in Mopy\Docs and Mopy\bash\l10n, which will be edited yet.
