* Add a test suite for the svn backend.
* Daemonize before sending RPC pings, since that can take a while
and/or hang.
* Daemonize before sending commit mails, as that can also take a long
time/hang if the mail server is unhappy.
* Factor out commit mail sending code into new function.
* Web commits by OpenID users will record the full OpenID url for the user,
but in recentchanges, these urls will be converted to a simplified display
form+link.
* Modified svn, git, tla backends to recognise such web commits.
