(Of course, also the transaction amounts have to be modified)

There is also a couple of changes in "vote fee":

-We decided for the moment to only allow values between 0.1% and 1% (in the contract's language this is between 10 and 100).

-The "updatefee" action was deprecated since now it is executed automatically each time a modification in the voting tables happen. Therefore we can remove "updatefee" from the voting transaction.
