Put save blueprint data into the link

[serg-bloim]

There are currently two options to save/share blueprints: save to file/clipboard and to save to a server.
Both have their downsides. I propose a third option is to generate a link with the BP data as part of it. It should perfectly work with small-medium BPs, should cover most of the cases. I only tried it for CoI, not sure if there's any difference for other modes.

This feature would allow to store BPs right in the browser, easily share with others, etc. The only downside is the size limitation of 2KB.

Another alternative is to keep the files in the browser storage. Like draw.io does for instance.
