feature request logrotate and delete old screenshots and html saves

[W-M-D]

The program seems to be working but I had a problem where it used all the space on my device by filling it up with screenshots. I'll try and see if I can implement it later but I think this needs a max data size variable before it starts deleting the oldest screenshots.

Logs already rotate on restart. You could also just periodically restart and delete old screenshots.
