Convert all tabs to spaces

[Wallacoloo]

Much of the code is mixed tabs & spaces. With the exception of the Makefile, all tabs should be converted to spaces (width=4).

The linux 'expand' command can turn tabs to spaces correctly. Eg expand -t 4 file > file2. To expand all files in a directory (recursively), inplace, use the following command: find . -name '*.cpp' ! -type d -exec bash -c 'expand -t 4 "$0" > /tmp/e && mv /tmp/e "$0"' {} \;
