Release 0.5.0

A default run of sass-spec found 1359 of 3331 tests passing (or 1416
of 6086 when claiming to be libsass). Changes since version 0.4.0
includes:

* Improve handling of quoted / unquoted strings and interpolation.
  Still not correct, but exhibits correct behavior in more tests than
  earlier.
* Support interpolation in selectors.
* Support interpolation in property names.
* PR #14: Implement map syntax and map functions.
* Make error handling not break if nom is compiled with verbose-errors.
* Miscellaneous internal cleanups, some suggested by clippy.

 If you want a working rust library for sass right now, you will
 probably be better of with [sass-rs](https://crates.io/crates/sass-rs)
