Spells/Attributes

* update spell attribute descriptions primary from TC, secondary from Wowdev Wiki (not guaranteed to be correct for 335)
 * show all attributes on SpellDetailPage
 * update links from attributes to SpellFilter
   * unsure: should the attribute filters work purely on attributes or also consider other factors?
 * implement some of the client side modifiers on the spell tooltips and buffs
