Pyro:
 * Health 700 -> 620 (below the 2 Defender threshold).
Jack:
 * Cost 650 -> 600
Moderator:
 * Range 410 -> 420
 * Significantly increased turnrate and turret turnrate.
Selection and deselection of a single unit with Unit Selections now acts on the unit icon which was clicked on. Previously the first unit of that type was selected/deselected. This should make unit control easier.
Removed fire time tracking complication in Outlaw death script.
Converted Slasher to LUS. To speed things up I copied the pivot script from the Dominatrix LUS and the suspension script from the Scorcher LUS. Both parts of those scripts turned out to be completely broken so I rewrote them.
Rocko:
 * Health 480 -> 450
 * Range 460 -> 450 (same range as before KR's buff).
Merge branch 'master' into balance
Shieldbot commit.

Dirtbag:

Bandit:
 * Cost 80 -> 75
 * Range 240 -> 245

Outlaw:
 * Speed 1.5 -> 1.9

Improved Bandit, Outlaw, Warrior, Venom, Redback, Duck, Archer and Pyro Unit AI. They are now more cautious with things which have lower range than them.
Implemented Sak's Phoenix hit reliability change (as he missed git).
