Mechtonic but a little better

I mostly wanted a version of Mechtonic where enemies didn't attack when the player did.  I don't plan to change the game drastically. These are all mostly quality of life changes.

• Enemies cannot hit the player during attack and stomp animations. This includes M-TA.
• The timer is easier to see.
• Camera restrictions are reduced allowing the player to see more above and below.
• Graphics look different due to being forced to update the unity version.
