swaynag: address some more of sircmpwn's comments

Fixes segfauls for any case where swaynag->outputs was not inititalized
including -h/--help, -v/--version, and invalid arguments.

Sets sane defaults for colors not given. Any color not given will
fallback to the default color values for type error.

Adds support for a hidpi cursor
