Feature/store (#2907)

* Added parametr in plugins for disable interface loader.

* Added plugin method for show/hide buttons in plugin's header.
And changed event "asc_pluginButtonClick". Now it can return string| number. (string - for header's button, number - for footer's button and close button).

* Fixed problem with NaN detekting.
