* x/stake: Limit the size of rationals from user input
This commit sets the maximum number of decimal points that can be
passed in from messages. This is enforced on the validate basic of
MsgBeginUnbonding and MsgBeginRedelegation. The cli has been
updated to truncate the user input to the specified precision. This
also updates types/rational to return big ints for Num() and Den().
Closes#887
