Preferences from Special:MobileOptions; "version" fieldEdit

In phab:T212516 and phab:T211197, we recently added the mfMode (MobileFrontend mode - i.e. beta vs. default) and mf_amc_optin (Advanced Mobile Contributions) properties to this schema.

BTW, regarding "Any change affecting the nature of the data collected in the log should be tracked by bumping the version number" - it seems that this never happened, the version number has remained at 1 despite the addition of various properties since 2013. (Or perhaps "nature of the data" meant something else, but then again we have the schema revision number for larger changes which has not changed since 2013 either.)
