Added menu and keybinding for ledger-post-edit-amount

editing the amount with calc is too cool for school.  I can't believe I didn't see it before.
It is in the docs now as well.

+@subsubsection  Calculating Values with EMACS Calc
+
+EMACS come with a very power calculator built in.  You can use it to
+easily insert calculated amounts directly into your ledger buffer.  From
+the menu, select @code{Calc on Amount}. Calc will pull the current
+amount to the top of the calc stack. Calulate the value as you normally
+would with an RPN calculator.  When you have the desired value on thetop
+of the calc stack, press @code{y}, and calc will insert the value
+in place of the previous amount.
