Fix clang-format-sublime plugin for Sublime Text 3

[Johan Engelen]

Hi all,
   Sublime Text 3 uses Python 3.3 for its plugins (instead of 2.6 that 
Sublime Text 2 uses). The attached patch fixes clang-format-sublime.py 
to work in Sublime Text 3.
I am not a Python expert, but it seems for this plugin, the only 
relevant change is that "print" became a function, so parens are needed.
I tested the change and the patched plugin works in both Sublime Text 2 
and 3.

Thanks for the review, (and commit ;)
   Johan
