Merge lp:~davidmhewitt/granite/fix-commandline-args into lp:~elementary-pantheon/granite/granite

[David Hewitt]

Ignore arguments that aren't recognised by granite

Currently, when granite encounters a command line argument it doesn't recognise (i.e. something that's not -a (about dialog) or -d (debug mode), it stops parsing and passes all arguments (including -a and -d) to the application to handle.

Because the application probably doesn't know about the two granite specific arguments, these are often unrecognised, see: https://github.com/elementary/appcenter/issues/76

If we add the line in this proposal, granite skips over the arguments it doesn't recognise and eats the ones it does. So granite deals with the granite specific args and the application gets the rest.

I can confirm that this addresses the issue
