Removed WIP and added more HUD

+ Added an alpha multiplier to the transition shader, allowing the
shader to appear transparent.
+ Removed the WIP folder from the github - It was taking too much space
- It will be local now.
+ Added some new HUD elements

- Need to fix up birds, spawn outside the scene and fly in, and do it in
a more robust way.
- Need to think of something that will spice up the HUDS, the current
style is not that interesting
- Update transition shader, either make it less or more faded at the
edges, currently too medium.
