Operator calls: extended WM_operator_name_call() with options whether to
call the exec() (operate immediate) or invoke() (check user input) entry.

This will allow python to use it more efficiently, but also solves the
dreaded pulldown case that showed another menu for confirmation.

New names to learn: :)
WM_OP_EXEC_DEFAULT
WM_OP_INVOKE_DEFAULT

on todo still: allow hotkey definitions to do same.
