prepatch bug report

[swallowsoul]

hey, I got this report from bugsack when trying to complete a quest in darkmoon faire, apparently if the quest requires things like archeology fragments or coins the UI bugs, and you can't turn on the quest.

1x Immersion/Components/Elements.lua:78: attempt to call global 'GetQuestCurrencyInfo' (a nil value)
[string "@Immersion/Components/Elements.lua"]:78: in function <Immersion/Components/Elements.lua:49>

Maybe a workaround (need more tests for sure):

diff --git "a/Components/Elements.lua" "b/Components/Elements.lua"

Thanks for the code @neun0eil, I'll add it to the wrapper.
