Update README.md

And created issues for the stricken items in the lists.
Fiixed continuous play and a few other bugs

* Fixed so that the queue can be played all the way. (Issue #7)
* Fixed skipping to next and previous songs in queue. (Issue #2)
* Regarding next and previous: this also makes sure that if repeat is
  on, the next and previous will wrap around and play the correct song,
* Now threading all the calls that can happen asynchronuously on the
  server. The only calls that are not threaded are the ones that require
  a reponse (such as show queue) (Issue #6)
* Added ability to shuffle current queue on server.
