primary keys from character strings to integers, and makes corresponding code
changes.
This was prompted by database limitations discovered when trying to make
DocAlias use a m2m document field; with 255 long strings as primary keys for
Document and DocAlias this violated the MySQL database limitations.
Changing the primary keys to integers should also improve efficiency.
Due to the data migrations which create the new integer primary keys and adds
corresponding integer foreign keys matching the previous string foreign keys
in all tables having foreign keys to Document and DocAlias, some of these
migrations take a long time. The total set of migrations are expected to have
a runtime on the order of 2 hours.

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.
