altered the way the way upSquirt pulse so that it holds it self on the stage better

added a spawnManager for testing Enemies
upSquirt behaves less erratically, i cant figure out the lerp though so it has  just locked the angle instead of lerping between the angles
added eye motif as child on upSquirt
animation added to upSquirt.
swapped sprite on Chaser
animation applied to chaser, still bit rough
added 'wobble' enemy, still needs editing of prefab and behaviour.

also made some minor clean ups changes to file structure.
wobble enemy animates and moves with state changes

still needs some tweaks
numerous tweaks and fixes to wobble enenmy
projectiles no longer collide with gibs and tweaks to wobble
