Add FunctionCallSpaceFixer

FunctionCallSpace fixer added to remove spaces from after function names (in function or method calls).

Fixes #681.
Soooo.. how about considering opening braces after language constructs as function calls only if the statement is terminated (semicolons) after the closing of the parenthesis.

That is fixing:

    include (__DIR__ . "/file.php");

but leaving alone:

    include ($count + 1) . ".php";
