Minor changes to job workings

Bards were not consuming TP very quickly in simulation. This is because Straight Shot was slated to use 60 TP instead of 70 (I took the liberty of correcting the wiki the error came from as well!).

The buff listed as "Heavier Shot" is the name of the trait; the actual name of the buff it grants is "Straighter Shot". I changed this, as it will not interfere with the bard rotation currently in the code base.

Dragoons as of 2.4 have shorter cooldowns on Spineshatter Dive and Dragonfire Dive. The new values are included in this pull request.
