The log update

Yay! After a month of working on this update (after what I originally thought would be 1 week, then 2, so on) I finally finished it! Introducing the log tree (get it?), an upgrade tree where you can spend paths for multiple upgrades. Buy paths with log points, but be careful, as the cost increases rapidly.
Changes:
-added base upgrade 4 (the second one, I know it doesn't make sense)
-added base upgrade 5
-capped ipsiClickers at 100
-themed buttons
-added the log tab
-added the base slider
-added the automation tab
-added the options tab
-added the log tree
-changed the font for the game
