This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
This fixes a few warnings/errors in the LUA code. I added some FIXMEs at the
places where the casts happen, since usually this casting indicates bad
design.
