VAM Plugin: Hide Error popups

A small cosmetic plugin to hide the popups for error messages (red) or general messages (blue) and instead only show a message counter in the main menu UI. If you click on the buttons below, it will still show you the messages that were brought up.

Update v1.1: 

- Added a settings script to show/hide the error and/or message counter (default: on).

- If you right-click on the error/message counter, it will clear the number of errors/messages.
