sort linux stuff into subcase
copy darwin subcase from 1.9.2 build.sh

TODO: Need to update this when I get a chance to build on Darwin
Add and update the msys subcase

TODO: Probably need to add to this later when I get the other deps building
fix DIR export

Works on msys, need to double check that this doesn't break linux builds
Temporarily prevent clobbering the build dir
Remove deprecated script
Remove MSVC8 mozconfigs
Add and update MSVC10 mozconfigs

Need to figure out if the exports at the end are correct... they seem to
be working though, but I'm not sure why the path formatting differs
depending on where I look in the documentation.
"fi" spacing ocd fix
Make sure the output subdir exists before trying to move things to it
