Personal store has been fixed

* Personal store is now able to sell the items for the specific price

exceed maximum silver size, the the silver is converted to gold once.
* Personal shop is now being updated correctly on both sides (seller and
buyer).
* Fixed action.js due to unnecessary debugging and caused trouble for
the testers.
* Character stat calculation on server side is now being re-examined and
planned to be fully coded.
