[openstreetmap-website] Usernames are not XML-char safe (#759)

[Andy Allan]

Usernames are changed directly through the web site, and don't go via the API. This means they can contain non-XML safe characters.

This isn't a problem using any XML API or dump, but could cause problems with e.g. history dumps.

They should be stripped of non-XML characters, c.f. https://github.com/openstreetmap/openstreetmap-website/blob/d27cc80b438b0943ac532b727b48b6ca6601f990/app/controllers/amf_controller.rb#L883
