Display Asterisk on Unsaved Documents (#392)

* ability to mark an open document as unsaved

* unsaved detection now being triggered based on layer tree height

* - rust implementation of unsaved markers
- upgraded eslint

* updated eslint in package.json

* - Renamed GetOpenDocumentsList -> UpdateOpenDocumentsList
- is not -> was not

* changed hash to current identifier to better reflect its meaning

* resolve some merge conflicts

* removed console.log statement leftover from debuging
