Support multiple files with tiny urls

[hackel]

This is an enhancement request. Woof should spit out a tinyurl-style link like http://192.168.1.1/t3s8z for each file. Once you share one file, any subsequent shared files should be added to a list maintained by the primary instance, each with a unique URL This is especially important since there is currently no GUI to see when one file has finished being shared, and it is too easy to try to share two files at the same time, which will fail.

There could also be a persistent option when sharing a file which will save that unique URL to be used again the next time woof is launched, though this functionality might be getting too close to a regular web server.
