Make matrix.org server default when logging in
When logging in for the first time, some users who created an account directly through Riot may not know/remember the domain they created their Matrix account on, and creating an account through Fractal defaults to using the matrix.org server. I propose following Tobias's new mockups to create radio options for using the Matrix server or a custom server, but even changing the example domain from 'myserver.co' to 'matrix.org' could prove helpful.
