Cannot save or otherwise specify filenames

[ziz]

Since there is no method for interrogating the client as to what filename to use for a save game or similar, one cannot save or restore using remglk at this time.

I have written an embarrassingly cheap hack to allow saving - basically, add a "savename" field to the line input you're returning before the system needs a filename.

Example message (specifying a SAVE command, with a savefile name of 'foobar'):

{"type":"line","gen":1,"window":30,"value":"SAVE","savefile":"foobar"}

I don't recommend this at all for long-term use, but if you're impatient like me, it'll get you by until a real solution has been devised and implemented.

This went in with the 0.2.1 release. When prompting, the update call contains a specialinput object, and the event that comes back has type specialresponse.
