Vidalia fails to build if spaces are in the build path

[edmanm]

If you try to build Vidalia from a location with spaces in the path, you will get errors like the following:

[ 36%] Generating vidalia_win_res.obj
gcc: and\: No such file or directory
gcc: Settings/zugu/Desktop/Vidalia/src/vidalia/res: No such file or directory
gcc: C:/Documents: No such file or directory

mingw32-make[1]: *** [src/vidalia/CMakeFiles/vidalia.dir/all] Error 2

This is really a CMake bug, but it would be nice to find a workaround.
