Updated to use a flow like:

- settings/two_factor_authentication goes to a #show view which has a button
  either enable or disable 2fa on the account
- the disable button turns off the otp requirement for the user
- the enable button cycles the user secret and redirects to a confirmation page
- the confirmation page is a #new view which shows the QR code for user
- that page posts to #create which verifies the code, and creates the recovery
  codes
- that create action shares a view with a recovery codes controller which can be
  used separately to reset codes if needed

This commit provides a heavy proofreading of zh-CN translations, and
mainly draws from the zh-HK source when a translation is found too
incoherent. Translating directly from en is used when zh-HK translation
is not available.

This commit also completes the tweet-toot (choo-choo, actually) for
zh-cn introduced in #2044. Some minor copyediting, as well as
additional en translations, has been fed back into zh-hk text.
