Removed Hit Button and Preps for S-AI changes

Removed the hit button from the gui and added a dummy method in smart AI for
changes that will be made for smart hitting.
Improved AI

new smart discarding based on value of cards
improved skipping now also bases choice on points
Hitting now Available for Smart AI

Theoretically, the Smart AI is now able to hit on a phase after it has phased
. I am unsure as to how well it works but, it hasn't crashed yet.. though it
hasn't laid a phase yet either.
