Merge lp:~cjwatson/launchpad/fix-dsp-vocab-picker into lp:launchpad

[Colin Watson]

Customise the picker for DistributionSourcePackageVocabulary to make vocabulary requests in the context of the currently-selected distribution.

Customise the picker for DistributionSourcePackageVocabulary to make vocabulary requests in the context of the currently-selected distribution. Otherwise the vocabulary only works if explicitly given the <distro>/<package> search format, which isn't very user-friendly.

I've also changed the vocabulary itself to return just the package name as the term's token and title, rather than distribution/package. This is less strictly correct, but given that it's always being fed into a package name text box it works a lot better in practice (we don't want that text box to receive e.g. "ubuntu/firefox"), and since the vocabulary always has its distribution context set from somewhere else it works fine in practice.
