Slightly improved bard rotation

Tries to use 2 oGCDs per GCD for the opener. There is nothing sophisticated to prevent this later in the rotation, so there is possible room for improvement. Tested quite a bit for overall DPS, but I can't be too sure nothing silly is happening. Suggested buff order from http://www.reddit.com/r/ffxiv/comments/2maeql//cm2oqfz seems to win over a few others I've tried by a few (split) hairs judging from simulations only.

This script assumes 100% Straight Shot uptime to work, otherwise that opener stuff at the top is probably going to mess something up (e.g. out of TP situations).

This ought to hold Blood for Blood to coincide with Hawk's Eye and Barrage. The effect of aligning vs. not aligning seems very minor in simulation, with a slight advantage towards alignment. In that case, aligning is better (less risk of taking damage, more windows for songs).

Straight Shot should be clipped if it will fall off before applying both DoTs (gotta have procs!).

Straighter Shot (guaranteed critical, effective potency 210) will be spent if it would otherwise be time for Heavy Shot (150 potency + chance of critical).

Other than the 2 oGCD and not being able to guarantee it works 100% correctly thing, I believe this reflects a number of DPS-only bard best practices. I don't play bard seriously, though.
