[Feature] Allow project actions to run without opening the terminal

[rwjdk]

Project actions are currently configured to open and focus the terminal whenever they run. This makes sense for interactive commands, but it is not cool for things like launching the App in a browser or doing something that should just run with no actions to take... Right now I need to run the Action, click the close button in the terminal, and confirm the closing of the terminal, defeating the purpose of "Quick" actions

I suggest we add a checkbox in the action configuration dialog called "Execute Command in Background"
