Fixed yet another issue with ElvUI's timer texts (they weren't going away when they should have been).
Apparently ElvUI's code is so broken that the last fix I put in wouldn't have worked - there is no mechanism in ElvUI to stop a timer if self.noOCC is true - it just returns early instead of checking that the timer is stopped first. Cool!

Added a changelog message about the SavedVariables serializer issue being fixed.
Wipe the class spell cache, and don't accept data from anyone using an older version of TMW than the user.
BitFlag conditions can now use tables when they need to store flags higher than 32. Which makes them not technically bit flags all the time. But oh well.
Unit conditions can now be configured with bitflags, and the UnitClass condition has been updated for this.
Clearing a slider's editbox now attempts to set it to 0, instead of failing to change anything.
Fixed an issue with sliders that was causing "Numerator must be a number" errors to be thrown when the value was excessively large - Slider:GetMinMaxValues() returns -1.#IND as its max.
Code formatting cleanup
Added a UnitSpec condition.
