savemanager.py: Use winpaths module to find AppData
Trying out bbfreeze
Set executable to spawn for multiprocessing module

bbfreeze ships a copy of the Python interpreter, so try to use that when
spawning a new process via multiprocessing. Hopefully this will make
things much faster than spawning savemanager.exe.
imag: close & join worker pool when done
imag: Add support for DXT1 compression, s/dtx/dxt/g
exposure_map: Show the whole unmapped coastline

Before I was just showing the coast within the "outline" portion of the
map just beyond the edge of the revealed part, but that doesn't exist
next to parts of the map revealed through collecting region maps, so
just show it all.
savemanager: Fix bug if the player hasn't picked up any plants yet
Rename savemanager -> Miaschiev

I wasn't happy with the working name "save manager", since it doesn't
really manage saved games, it shows achievement progress. So, rename it
to "Miaschiev".
bbfreeze hacks for gui_only + multiprocessing

miaschiev: Delay processing auto-detected paths

So the window gets drawn early and the user can see what's going on.
