Update 75

-Flash time remaining is now set to the base time rather an added when flashing the same color
-Flashing times are now independent of frame rate (seems like it was still pretty consistent prior, but it should be slightly more consistent now)
-Added a separate parameter for whether flashing should give "Flashing Invulnerability" or not (rather than flashing giving it by default)
-Healing flashes no longer give invulnerability for the duration of the flash (only really applies to the Player and Minions as most other creatures can be hit regardless of flashing)
-Minor optimizations
