Snip v2.6.0

* Added SimpleJson as a way to parse json easily.
* Changed project from .Net Framework 4 Client Profile to .Net Framework
4.
* Added a reference to System.Web so HttpUtility.UrlEncode() could be
used.
* Changed the way album artwork and track information are discovered
with Spotify.  It no longer tries to get the exact track ID within
Spotify's memory.  It will now query the Spotify API on the web using
the artist name and track title.  If a match is found it will pull the
track ID from there and then query the regular Spotify HTML page for
artwork.
* The change above allowed me to remove a lot of unnecessary code,
including ReadProcessMemory(), GetWindowThreadProcessId(), and
FindInMemory().
* Removed some unused WindowMessage commands.
