Funny Skeletons

There are now skeletons that will spawn in during waves.

A new enemy has been added

This new enemy has a shield that will take ~2 hits to destroy. After the shield has been destroyed the enemy will gain a slight speed increase, but now the enemy can be damaged normally. 

Two new towers have been added

Beam: low damage, but can slow enemies. This tower can slow an enemy to a crawl with help from an additional beam tower.

Alchemy: low damage, but high fire rate. De-buffs enemies with a damage over time effect. This tower has a limited amount of shots, but will generate new shots over time.

Gems gained after completing a set of waves have been changed, as well as the starting amount of gems.

Adjusted how much stronger enemies got after a new set of waves.

The intro now has some text that will tell the player to stand on a node and select a tower after going past the text that tells the player to hold Q for the build menu.

Heavily altered the nav mesh for the level after the intro.
