Merge pull request #3 from intangir/master

allow normal villagers to be hired also, and leave citizens2 npcs alone
hireOtherVillagers setting now defaults to 'false'
msgForHire was renamed to msgVillagerForHire
added otherVillagerHireCosts
Change: if trades with other villagers are not disable, but hiring is
enabled, it will no longer block trading if no hiring occurred
The items in the trade menu slots now also have to match the needed
amounts of their corresponding slot.
This change is only meant to react to possible confusion of users about
trades being allow even though the slots don't match perfectly (because
minecraft does not caring about concrete slot matches as long as the
overall trade matches).
