Specifying multiple parameters when stating operation signature doesn't match

[Matthias Schoettle]

When specifying an operation signature with more than one parameter it doesn't always match. The delimiter "," of parameters cannot be followed by a whitespace.

Steps to reproduce:

1. Create an operation with the following signature: + void foo(int x, int y)
2. Press enter.
3. The signature is not accepted.

The GUI should accept both cases, just the delimiter or the delimiter followed by a whitespace.

Fixed issue #50: The parameter delimiter can optionally be followed by a whitespace.
