Plowing!

Updated Goblitairation!

Added a blinking cursor. Thanks to Daniel for the sprite!

Removed alternative bounce rules - turns out they were less intuitive than standard bounce rules.
Added plowing. This currently has some minor animation glitches when corners are involved. However, they do not affect game play.

Removed rotation before first move for now. I'll be adding it back later.

The code for plowing was so hard!!! I wanted to delay moving the plowed ship until it was actually hit by the plowing ship and that proved to be sufficiently difficult. There were several edge cases to account for (sometimes it helps to have a good testing background).

Hopefully I should have a chance to add damage tomorrow. Should prove to be much easier than plowing.

Feature Spoilers!

An interesting note about the implementation. The player's move is planned out in advance and stored in an array of cells to visit. Animating that plan is done after the entire move sequence (including plowing) is calculated. The ship is stationary while the planning is done thanks to state-of-the-art data structures and magic. This will allow the animation to be played as a preview before the player confirms card choice.
