fixed skills tooltips

heroMethods:
--update would set wrong property

itemMethods:
--getItemType would return Bracers_Crusader for example.  used indexOf
to fix it.

playerMethods:
--insert and update Hero's Paragon property is now paragonLevel

hero.ejs:
--if hero did not have an extraItemData, page would not render.  fixed
this.
--a skill's link would only replace the first instance of " " with "-",
and did not replace "'" with "", therefore, not linking to the battlenet
site and showing tooltip
