Add a list of various global constants
Redesign the game to just use the libgdx Screen interface
Progress advanced quickly, I have most of the UI complete with even field texture scroll.
Also we're not using the AssetManager for loading things.  This is a lot safer than directly loading and is threaded.
Properly sorted a lot of the images

Sorry for the big commit, I know this is messy
Redo the Stat bars and key display and add the disc to the keys ui
Try making the score field.  I'm having a bit of trouble getting the text to display
Input should be fixed now, apparently input listening of keys doesn't chain down the stage
Do a lot to get the player and field rendering in its own section
Player is able to move around
Banners pop up when low ammo and low hp notifications are sent by the player they are observing
Create an Entity System using Artemis Entity System.
Here's all the components to be used as well as their systems
Field display is handled entirely by the RenderSystem now
I forgot, consts are now a package instead of a class with contained classes
Convert Player to be an entity generator
Add entity based bullet emitter
Use an xml file and png to create an enemy atlas that can generate entities
Levels parse an xml/svg file and have their own entity system.
Add example content files for svg parsing and using in levels
Change the Scene to use the new level and entity system
New set of bullets
Continuing to alter the Level format
Added things like layered backgrounds
Move the world stuff into the Engine and just purge it on new level load
Move around a lot of the components and add ComponentTypes for faster manipulation
Fix up the level background with the new files
