Add a FAQ to the wiki

[Mattie112]

Would it not be a good idea to add a FAQ to the wiki? The first item I would suggest is "I lost my password, what now?"

It seems you can't make a pull request for the wiki on github so yeah...

In progress as part of #404

Git's wiki system is a bit convoluted to edit externally, so we have to suggest, and/or link to our own edited copies without being granted edit permissions.
