Critical Hits now affect boss damage fixes #5429 (#8092)

* Moved critical hit calculation from _addPoints() to _calculateDelta(). Added user as an input argument to _calculateDelta() so for critical hit calculation

* Changed test to expect task value of 1.5 after critical hit

* Revert "Moved critical hit calculation from _addPoints() to _calculateDelta(). Added user as an input argument to _calculateDelta() so for critical hit calculation"

This reverts commit 51b8ab6498.

* Moved critical hit calculation to _changeTaskValue(). Use value stored in user._tmp.crit in _addPoints()

* Test is no longer affected by critical hits

* Removed unneeded comment

* Added WIP test of critical hits

* Want the crit function to return 2 to test critical hits

* Changed crit function to export as a function within an object so that it can be stubbed for testing. References to the crit() function were updated to call crit.crit() instead

* Added test for increased experience on critical hits
