Reorganize FAQ

[ahuang11]

Start FAQ with questions about common things like how to label, re-range, adjust size, legend, and exporting, then some miscellaneous questions, and lastly advanced customization.

Looks great! I think this ordering makes much more sense. Can you state explicitly that only the ordering has changed, not the content? It's hard to be sure of that because diff doesn't work well for reorderings, but if you say it's true that's good enough for me...

[jbednar]

This bit seems like it should move up to be merged with the earlier question about how to size plots in mpl and bokeh.

[ahuang11]

maybe keep this PR for just reorganization and do that in another PR?

[jbednar]

Sounds good!

[ahuang11]

@jbednar only the ordering has changed!

Here's a quick check with Word:
2340 words on left (original); 2340 words on right (reorganized)

[jlstevens]

Makes a lot of sense to me!

[jbednar]

I can't see why the tests would be failing for this PR; I've restarted them, but to no avail...

no idea xD

Not sure what's up with those test failures, seeing them on other PRs too. I'll update the test data and then rebase this PR once it's fixed.

[philippjfr]

@ahuang11 Would you mind rebasing the PR against current master? I've rebuilt the test data so the tests should pass then.
