Fix some raid buff checks so that they may be cast by anyone.

Fix some raid buff checks so that they may be cast by anyone.

The affected buffs/debuffs are:

    mastery
    str_agi_int
    stamina
    spell_power_multiplier
    weakened_blows

Rename the buff aliases for burst_haste:

    bloodlust -> bloodlust_aura
    heroism -> heroism_aura

This should allow shaman scripts for both Alliance and Horde to define the
spell names with the same names granting buffs of the same name.  When
checking for the burst_haste buff, use one of the following buff class
names:

    burst_haste
    bloodlust_aura
    heroism_aura
