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
