Simple :JavaRunnerClose cmd #344

Did you check the docs?

• I have read all the docs

Is your feature request related to a problem? Please describe.

Whenever a program stops, I have to stay on the terminal and use the classic :q cmd. So my problem is kind of a silly one, I use lualine, and because there is no 'close the runner' command, I can't add a button to my lualine to close it.

Describe the solution you'd like

If you could simply provide a nice JavaRunnerClose command so I may add it to my lualine configuration. It should just close the terminal left open when a program finished, or even still running.

Describe alternatives you've considered

• Tried some rough monkey-patching, but it doesn't appear the Runner/Run class is a singleton, so I wasn't able to get that working with my short attempt...
