Walking papers mode

[Zverik]

A fourth mode that allows scribbling lines on top of a map / imagery layer. No uploading anywhere, but with a option to export to geojson. Below two rows of buttons: colors for roads / buildings / paths / fences. And "undo", "eraser" (later, too hard to make), "add a note". The latter can optionally be uploaded to OSM — which solves #47. And in time photos can be attached there as well.

Pavel in the chat adds that it would be nice to have different legends (buttons) for different tasks. E.g. surfaces, "lit=*", paths and streams, etc. Probably it could be a single big list of things, but with a manual assignment of colors and buttons.

Types I used in my walking papers:

• Road and track (not paved + unpaved road, since surfaces are aplenty) — white thick
• Footway and path — red
• Cycleway: designated and shared — purple
• Wall and fence — yellow
• Power line
• Stream (and ditch/drain?) — blue
• Free-form writing — white

That makes for 6 colors + white. Second option is dashed / dotted line. Attributes like lit can be improvised, steps can be drawn as perpendicular footway.

These should be uploaded to a central server and be shared as tiles. Data would be purged there in 4-6 months. Button to clear the view in the editor.

For un-uploaded changes, add a line to the changes panel, and add a button to share scribbles as geojson.

For map notes (not osm), which should be very short, show a list of previous / nearby notes. Useful for marking surfaces and other data.

All I know is if these are personal notes and not OSM Map Notes, then I would pick a different name: mumbles, etc.
