Add FunctionCallSpaceFixer

FunctionCallSpace fixer added to remove spaces from after function names (in function or method calls).

Fixes #681.
The parenthesis are removed by [IncludeFixer](https://github.com/fabpot/PHP-CS-Fixer/blob/master/Symfony/CS/Fixer/Symfony/IncludeFixer.php).
So maybe we may simply remove `T_INCLUDE*` and `T_REQUIRE*` tokens from list inside `getFunctionyTokens` ?
