Fix rrset changelog for names with hyphen

Browse Source 
When clicking the changelog button for a record with the name
`foo-bar.example.org`, the url you get redirected to is
`/domain/example.org/changelog/foo-bar.example.org.-A`. Because of the
non-greedy behaviour of the path converter, the last part gets split at
the *first* hyphen, so the example above gets wrongly dissected into
`record_name=foo` and `record_type=bar.example.org.-A`. This results
for obvious reasons in an empty changelog.

As described in rfc5395 [0], types have to be alphanumerical, so its
converter is changed from path to string.

The hyphen is one of the few characters recommended by rfc1035 [1],
so it is a bad choice as separator. The separator is instead changed to
a slash.
Granted, this does not entirely solve the issue but at least makes it a
lot less likely to happen. Plus, a lot more and other things break in
pda with slashes in names.
