In routing-preview, the title should be the branchname attached to the
subscription instead of the libraryname.
And showing the streetaddress of the members is useless, and harm privacy.
The issue descriptor was not being escaped before being passed on to the
routing slip, causing truncation. It's truly impossible to know for sure
what will be there, so uri_escape-ing seemed the best way to ensure that
it gets handed forward and makes it all the way to the printable slip.
