Fix ticket #213 - Issue with Monk Energy Regeneration.

Fix ticket #213 - Issue with Monk Energy Regeneration.

This fix has several parts.

Firstly, there was an error in energy regeneration calculations where the
percent haste effect wasn't properly scaled.

Secondly, the Way of the Monk passive effect will increase melee attack
speed by 40% but we have to remove it from the melee haste effect when
computing energy regeneration as that attack speed bonus has no effect.

OvaleEquipement has been extended to cache the weapon types of the
mainhand and offhand slots so that they may be easily checked.
