majoris design note:
we saved all jsons used in database (in appconfig,panelconfig,serverconfig tables)
here. but for now in version 2.0 we only compare appconfig.json, apptext.json, webconfig.json and panelconfig.json files
with the json is already stored in customer db. so when we user update the panel 
we cant recognize the diffrence and update the customer db. (in dasbaord of panel for now)

also note that we can do more good thing with default jsons. like storing json of structure of tables like posts
and compare and update the database stucture in realtime.
