Another bug-fix spree.

A lot of time was spent on figuring out how to fix the abusable ‘squishing’ mechanics where you could effectively jump through a block before the squish detector would go off.

• [FIX] bug allowing you to rotate warpgates whilst away from them if you back out part way through a rotation
• [DEV] address death screen console errors
• [DEV] Make dialogue setup more generic
• [ADD] Time based lighting now fades rather than jumping between colours, and colours made less harsh
• [DEV] Move rain to canvaslayer to ensure it ignores camera2d zoom and reduces the amount of particles necessary to draw
• [ADD] Open / close inventory player animation, UI animation, and sounds
• [FIX] Block squish was abusable
