Improved date/time parsing and closed captions

The release introduces two features:

• Add closed captions to writer. Refs #79, #80 Thanks to @mbowBC for this contribution.

• Customizable TimeParse() function allows broad support for time formats beside RFC3339. It allows parse playlists for devices that not strictly conform dates and times standards. By default it uses FullTimeParse() that implemented parsing that follows date representations from ISO/IEC 8601:2004.
  Refs #78 Thanks to @md2k for this contribution.

• Comments slightly polished.

License changed to BSD

This release has no new features or bugfixes. It just moved license of the project from GNU GPL to BSD. See the new LICENSE in the root of the repo. Previous release v0.8 and the versions below available under GNU GPL v.3.

More explanations in the issue #71 and in the release notes of the previous release. If you have complains please create an issue or drop me a mail.

The bugfixes and upcoming license changing

There are a lot of bugfixes and optimizations.

This is the last release under GNU GPL license. As decided by the maintainers of the project the code from the next release will be covered by BSD 3-clause license (#71). It will allow usage of m3u8 package in any kind of projects include the projects under proprietary licenses. It is no problem for GPL projects as conditions of GPL license allows include the code under BSD-licenses.

So the next release v0.9 will be with the same code but include the new license. The code of the version 0.8 and below can be used under GNU GPL.

There are a lot of contributions was made since the project started. As initial author of the project I very glad that this piece of the code was useful and attracted other people for participating. I am very grateful for all the participants for their contribution to the project! So if the conditions of BSD license totally inappropriate for a contributor and he don't want to see his name among authors of the code under non-GPL license then he can create the issue with a complain or just drop me a mail. Then I will remove the patches from this contributor and replace them with a new code under my authorship. I not sure how it is correct from the view of law but m3u8 is amateur project for me so I don't want spend many time for license questions. It is the code only matters.
