Screen MemStore (#197)
* working on an in-memory store for screen information * nostrpos sentinel * textareainput now tracks selection (to update backend) * make websocket connections much safer. add a defer/panic handler for each ws message handled on backend. don't allow client to reconnect to backend ws handler more than once per second (handles issue with lots of fast fails) * use onSelect to have frontend textarea sync state to backend ScreenMem store * restore cmdline when switching screens * prettier
