[imp] Filters : field name does not get translated

This just didn't make sense to me programmatically - storing "To:" in the 
actual filter storage doesn't make sense, especially when the only reason to do 
so is to match the UI. The UI shouldn't dictate how something is stored... So, 
I changed it back, but left the UI how you had it.
