Network communication should be asynchronous

[naoliv]

While the plugin is downloading or updating some notes, everything in JOSM seems blocked until it finishes to download/upload data.

The communication (getting notes of a bbox and posting comments) should be asynchronous (non-blocking).

The notes plugin is essentially dead and this is not going to get fixed. Instead, note functionality is being moved into JOSM core where notes are downloaded similarly to GPS traces, via a checkbox in the download dialog where it displays a progress bar and such. It isn't complete yet but it is already functional.
