Wait For Debugger shortcut for Godot Mono projects

Adds a checkbox next to the "Build" button in the top fight. This will allow you to quickly turn the setting on and off. Once the plugin is enabled, please only use this option to turn the setting on/off. There is currently no way for it to stay in sync if the setting is changed through the project settings. Please turn the plugin off and then back on if you do in fact change the setting through the project settings.
