New issue generated by not letting Talented handle the CONFIRM_TALENT_WIPE event.

The line in core.lua,
local dialog = StaticPopup_Show("CONFIRM_TALENT_WIPE")
causes the error,

bad argument #1 to 'SetFormattedText' (string expected, got nil)

This suggests that an additional argument is required, and the entry on WoW's gamepedia supports this:
CONFIRM_TALENT_WIPE: cost, respecType

But providing 1 or 2 string arguments produces the same error.
