[Docs] Community section

[joecritch]

• A "Community" section has been created, to house both the previous "Support" section and "Community Resources" docs category
• Separates the concerns of documentation vs. community, with the primary goal of cleaning up the docs nav (See Docs nav is too noisy #1669)
• Old permalinks supported via redirect_from field
• Note: Recommended to merge [Docs] Added icon for external links in nav #6090 first, so we get icons for external pages.

I think the nav title should be "Community & Help" - I wouldn't look to "Community" for support-related stuff as a first instinct.

[joecritch]

I personally disagree, as 'Community & Help' signifies that the help wouldn't be coming from the community. Also, FWIW, Ember.js has support inside of Community.

I wouldn't consider the Ember website the gold standard of information design.

[joecritch]

Me neither, but convention can go a long way. If anyone shares @yaycmyk's concern here, shout out :)

Community is one word like all the other heading in that section, seems like a good thing..

Added a "More From Facebook" category, similar to "Complementary" on the Flux site. (I went with "More From Facebook" to distinguish against non-Facebook led projects)

Thanks for the PR. I'm closing because we released new version of docs with a Community tab:

If you have ideas about improving it, please submit a PR against master and assign it to @lacker. Thanks!
