top level distros page could be improved

[James Troup]

Every time I visit https://launchpad.net/distros (usually on the way to report a bug) I'm frustrated by a couple of things:

 (1) This list is sorted alphabetically, but really shouldn't be. At the very least Ubuntu should be at the top of the list. The read only distros should be sorted separately from the read-write distros and we should probably sort each set by popularity or something similar.

 (2) Only Debian is marked readonly but there are are several others on there that should be also (e.g. Fedora, Fink).

(3) The right hand column ('Domain name') is impressively pointless and should be removed and/or replace by something more interesting and/or useful.

(I notice that Ubuntu is now at the top of the list at least - thanks for that)

This ordering is fixed. The read-only asterisks should depend on official launchpad usage, not the hack in the model.
This bug can be closed when distros-index.pt uses something like this:
