A couple improvements in these 2 commits:
1- alphabetized providers list to see what is going on in there
2- changed the regexes on \S* to \S+ as the assets in a directory are embeddable, not the directories themselves.
3- added support for the current providers listed in the oEmbed spec
4- added support for the providers listed in wordpress's core distribution
- added SoundCloud oEmbed endpoint
- alphabetized endpoints so we can see what is supported
two more improvements:
- changed \S* to \S+ where appropriate ( the assets in the directory are embeddable, not the directory )
- ported current oEmbed spec and wordpress-core supported providers
Thanks so much, looks nice!
