New features:
* added a new wind tower skill (increases base attack speed)
* added a "can be frozen" target priority to the frost tower
Polish:
* dropdown menus will now consume mouse scroll wheel input
* reworded some tooltips
* reworded the wind hit count skill
* changed "most essence" to "has essence" (picks enemies if they have essence)
* optimized the tower attack code (should be a small performance improvement)
* added another buildable location to vision 3
Balance:
* reworked how much relative power each skill gives per point applied (mostly increased)
* slight changes to almost all towers (not all listed here)
* changed the default target priorities for most towers (absorber most noticable)
* reduced water tower range to 2.5 (was 3)
* max wet stacks is now 100 (was 40)
* slow per stack of wet is 0.5% up to a max of 20% slow
* water tower bonus damage per stack of wet is now 0.01 (was 0.0125)
* removed wind tower ramping attack speed ability and skill
* decreased wind tower attack speed to 7 (was 8)
* increased wind tower extra hit charge to 50% (was 10%)
* reduced dark tower range to 7.5 (was 9)
* increased light tower range to 9 (was 7.5)
* reduced the difficulty of vision 2, 3, 4, 5a, 5b, and 6a (if this difficulty goes well, all the maps will follow)
* reworked vision 6b (it will probably feel more difficult, but it's technically easier)
Bug fixes:
* fixed wind tower extra hits not working properly when upgraded
* fixed light tower occasionally attacking non-existent enemies
* resetting skill points will now update the skill tooltips
* fixed target priority system it should work as intended now
* fixed absorber essence leech giving no essence
