MIPS syntax highlighting

There aren't a lot of IDEs for MIPS assembly (shocking, right?) I made an xml for gtksourceview to do syntax highlighting for MAL; you can find it on github. This will work for any editor which allows gtksourceview (e.g. gedit).

You will need to move it to the appropriate folder, probably /usr/share/gtksourceview-2.0/language-specs.
