-In makeconfig.ui, made the combo box for root installation command editable
-In makebuilderconfig.kcfg changed suCommand's type to string from int.
-In makejob.cpp Added a simple regexp to split the input command appropriately so that arguments pass correctly.
Reasons to accept this patch:
-Users will be able to pass any argument that they want (or remove any they don't)
-Some distros ship those binaries with wierd names such as kdesu5
Reasons not to accept this patch:
-You can get random commands to execute by entering it in the editable combo box
Although you can get random commands to execute by entering them in konsole, but that isn't considered
a security flaw :)
