v0.12.13: Fix PyMOL selection syntax rejected by PyMOL 1.8

The PyMOL selection syntax the code has been using has been working up
to PyMOL v1.7.2.1 (eg with Ubuntu 16.04) but is now rejected by PyMOL
v1.8.2.1 (eg in Ubuntu 16.10).

The code should have been using either a leading or trailing slash but not
both.

Fixes #12.

Add resolved boundaries to output and HTML

v0.12.11

Update HTML code to exploit new boundary resolving

v0.12.10: Correct mistake in how I'd applied CATH criteria

Under the CATH rules, Jon wants domains with suspicious HMMER evalues to
have their bitscores reduced by 4, even if they have dc_... IDs. I
mistakenly replicated some previous code that didn't reduce scores for
dc_... IDs so I'm fixing that here.

v0.12.9
