Summary: Make name the primary key for DocAlias.

This fixes Javascript widgets working with DocAliases, such as the
replaces field in draft submission, to work better with Javascript
disabled. It also makes sense from a modelling perspective as the name
really is a unique key for the alias.

The actual transformation requires a series of migrations taking a
couple of minutes to complete. The actual switch to the key is done at
the end.

Branch ready for merge.
