questhelperredux/QuestHelper/flightpath.lua
Nathanial.C.Jones 965e8589c9 Everything SEEMS to work, less of course the db. Something I did before screwed everything up.
I implemented a QuestHelper_GetTime function for the next time Blizzard decides to fiddle with the time functions. It returns debugprofilestop() / 1000, to exactly match the precision of GetTime().

I also re-removed references to Cartographer from the rollback.
