Support for video/mp4, video/ogg, video/webm

Added support for the three leading HTML5 Video mime types
.mp4 video/mp4
.ogv video/ogg
.webm video/webm

When Internet Explorer 10 or 11 receives application/octet-stream as the mime type for HTML5 video, it will not play the video. This resolves the issue in an Apache/mod_mono environment.
Support for audio/ogg and audio/mp4

.ogg, .oga audio/ogg
.mp4a, .aac audio/mp4
http://tools.ietf.org/html/rfc4337

Fix assertion in test-mono-linked-list-set

When running 'make check', test-mono-linked-list-set fails with:

* Assertion at hazard-pointer.c:353, condition `small_id == i' not met

This happens since 71ad74dc11c5fa4bc8c178a5457d2cab732fdb01, because
that commit changes the behaviour of mono_thread_smr_init() so that
invoking it should not be invoked more than once.
Style on the README file, make it more readable for command line users
