Long code cannot be shared

[aversey]

Since the share function currently puts the whole code in a query string, and a URL length is limited (browser-dependent, on my machine for Firefox the limit is around 8000 characters), long code cannot be shared.

I suggest using key-value storage with hash of code mapped to the code itself. Then “share” button computes a hash of code, saves the pair in storage and returns the URL with the hash.
