Version 0.5.1

[Bugfix] - Fix python 2 import (#134)
[Bugfix] - Fix two bugs in the internal backend (major bug remains unfixed)
[Update] - Remove deprecated signature argument

-------------------------------------------------------------------------------

28 February 2016
Version 0.5.0

[Feature] - Support both youtube-dl backend and internal backend (old 0.3.x
            branch. This makes youtube-dl an optional dependency, though it
            is more stable and thus recommended. There will be no more 0.3.x
            releases, as this eliminates the need for them.

            To use the internal backend even if youtube-dl is installed, set
            the environmental variable PAFY_BACKEND to "internal".
[Bugfix] - Fix UnicodeDecodeError(krishnawhite) (#129)

4 October 2015
Version 0.4.1

[Bugfix] - Fix Pafy.streams

-------------------------------------------------------------------------------

4 October 2015
Version 0.4.0

[Major Update!] - Pull in youtube-dl as a dependency, replacing current 
                  stream code [#109]

This is a major change, and will likely prove controversial, so version
0.3.76 has been released concurrently with all the changes not related to
youtube-dl. This makes the code simpler and easier to maintain while fixing
various bugs, but has some disadvantages.

If this is a problem for you, please use version 0.3.76 AND state your reasons
and suggestions at issue #110 on Github.

This version should be fully backward compatible with the previous version.
Pafy objects retain the pafy.streams list containing regular streams as before (video + audio)
In addition, there are now two new stream lists;
	pafy.audiostreams is a list of audio only streams (m4a and ogg vorbis where available)
	pafy.videostreams is a list of video only streams (m4v)
Further, there is a pafy.allstreams list containing the union of all three aforementioned lists
