DebConf8 hacks: better PTS/Lintian integration

Yesterday nigh hack: better integration of the PTS with Lintian.d.o.

Quoting from the filed misc developer news:

=== Lintian and the PTS ===

The integration between lintian and the PTS has been improved. On one hand
now the hyperlink to the Lintian will be shown for a source package only if
Lintian had something "to say" about that package. On the other hand, if
there were warnings or errors in the last Lintian ran, they will be shown as
TODO items in the appropriate part of the PTS web interface.

The display logics is as follows:

 * if there is 1 or more amongst errors and warnings they will be shown as TODO items
 * if there is 1 or more amongst errors, warnings, and information messages, the hyperlink to the Lintian report will be shown

Some more info are available in the bug logs (Debian bug #458329, Debian bug #243729); if you want a sample page have a look at ocaml, but I'm pretty sure that most random package pages will show at least 1 lintian warning in need of your love :-)
