[Anthony Lenton]

Fix screenshots and reviews.

A fix for two issues uncovered during testing:

- The review page crashes for packages with colons in their names. Afaik this is an issue only for multiarch packages (that's why they picked that separator). See for example http://catalog.razorgirl.info/cat/applications/oneiric/skype:i386/reviews/
http://catalog.razorgirl.info/cat/applications/skype:i386/ is even funnier.

- The screenshots page fails when there's more than one app for a given package name (this includes the same app on two different distroseries). See for example https://catalog.razorgirl.info/cat/applications/screenshots/hedgewars/
