Convert Stage 4

I've added another stage to Convert. Some other additions...
-The title screen now has a stage select.
-Pressing "r" mid-level will restart the stage.
-Pressing escape will return to the title screen.
-New enemy and spawner, Gants and Gant Mound.
-Sentry Mode, click on a unit to turn on/off their sentry mode, costs 10 energy each time.
-Pilgrimm sentry will reverse the move direction of friendly units.
-Strigrimm sentry will temporarily increase the move speed of passing friendly units.
-Sturgrimm sentry will stand guard and slowly regenerate hit points.

I REALLY need to get a separate page for this.

More on Gants and Gant Mounds
So the Gant Mound is a destroyable spawner that is aligned with neutral territory, so if the ground under it is converted to anything else, it gets destroyed.
The Gants are a fast spawning weak unit that move erratically, and converts land by slowly draining energy from it.

More on Sentry Mode
Pilgrimms can be used to round up your units for a massive push, or keep them from wondering into danger.
Strigrimm can be Sentried at intervals to make other units reach the front line quickly. How this works code wise is, the Strigrim's maximum speed per step gets applied to the passing Grimms, and this effect lasts for 3 seconds.
Sturgrimm regenerate their HP based on adding their speed to HP every second.

What's Next?
At the moment, I have 3 more unit/spawner types planned, and another special spawner.
