0.0.7

I had some more features planned for this one, but it ended up being mostly fixes. There'll be some new stuff in 0.0.8.

fixes:
-removed space bar control mode switch
-lock controls on pause/death
-fixed camera bounds
-fix a bug which permanently altered speed after picking up a boost while a boost was already active

changes:
-adjust bloom settings
-shrunk shield graphics
-interpolate shark rotation
-enemies will now only shoot within a certain distance
-pickups despawn
-moving diagonally with WASD is no longer faster

known issues:
-aiming with the mouse near walls feels weird as it isn't centred on the shark. Addressing this next patch.

if you find an issue, please let me know or raise an issue on the public repo!
