[b38 svn] Cursed Sentry slows down when leveled up

[richardhawk]

The intent seems to have been for the sentry to attack at 60% of average speed at level 1. Instead it has attack speed 60%, which is much faster than average. It slows down when more talent points are put into the talent.

Edited:

I've done a SVN diff and attached it as a txt file for the cursed-aura.lua file. This fixes the attack speed, makes the attack display clearer, and also makes the armor the weapon has more meaningful by applying a hardiness bonus based on talent level.
