Zeta 3 Update

These Zeta updates contain new improvements to the games controls, adds new enemies, and provides new quality of life improvements

The controls were overhauled to have the fire cannon button to the right mouse button instead of the left, now the player can close all the panels when firing automatically and not get stuck in the select mode. The help menu was updated accordingly and features a new organization to the controls display

3 new enemy variants were added, there are now lite and medium roamers and orbiters and bombers. They have different speeds and take different hits. So now there are 7 UFO types

There is also a new loading bar for loading the game scene and some of the console text readout was changed

There is also a new warhead for the munitions plant called drill bit, this adds a second impact to an asteroid to help destroy a nested asteroid

I am always squashing bugs too some notable ones were that the Sat-Turret gun system was shooting the scatter shot incorrectly causing them all to move in the same direction but that's fixed now and the bosses were getting targeted by the Sat-Turrets
