Do not recalc fits on tab switch (#1105)

* Do not recalc fits if they are already calculated. Fits that are projected onto other fits recursively set their victims to `calculated=False` so that the victim will re calculate when it loads again.

* Reset boosted fits when calculating a fit that is boosting others. Also, remove semicolon due to habit :x

* Develop a `__resetDependantCalc()` which will reset any fits that are immediately affected by the current fits calculation.
