Default implementation for collide()

Since all entities other than the Sword were doing the same thing on
collision anyway (dying), it makes sense to make death on collision
be the default behaviour.
GameScreen starts with a StartState

Continuing in the fine tradition of actually hooking bits and pieces of
the game up so they work together, the GameScreen actually has a
starting GameState (a StartState, appropriately enough).
Fix classpath

Somehow the classpath for the android project was out of whack. This
should fix it-- it at least does the trick for my configuration.
Add ballistic projectile

On update the ballistic projectile will be affected by gravity.
Add starter images

Some basic images have been added. They're definitely not staying, but
it's nice to have some images to work with.
Hero fields instantiated more completely

All of the textures, shapes and sword positions for the hero are now
defined for every hero state. Granted, this implementation is far from
complete, but it should get the job done for now.
Change handling of global InputHandler

The global IH is now at least read-only for everything other than the
main game class. Hero has been updated to make use of a HSM.
Add temporary image to Sword

The Sword now has a selection of Animations, all derived from the same
temporary image. It also controls its own position in order to retrieve
its renderables correctly.
Add android.jar to project internal directory

Change the android.jar reference from an external jar to a
project-internal one to avoid breakage.
Get base game displaying hero and sword

Lots of renaming things (sad face) in order to follow conventions. I thought I was smarter than all of that, but it seems that I am not.

There are a few changes to draw things properly with rotation as well as new positions. Development can continue as normal, hopefully with more testing. Overall, fewer crashes than I was expecting.
Sword position changes on input

Based on the user's input, the HSM (which is working surprisingly well for having never before been tested) will set the Hero's state, which will in turn update the Sword's state, which will update the sword's position when drawn or retrieved.
