Refactored Repo db access from DB class to ContentProvider.

The performance improvement from this will not be noticable (perhaps
there isn't one), however it is part of the bigger plan to move all of
the DB access to ContentProviders. This will make a big improvement to
the startup time of the app, given we are currently loading all of the
apps to populate the list of apps.

It will come at the cost of some apparantly weird code convensions. Most
notably, when loading data from a content provder, you only ask
for the fields that you intend to use. As a result of my Helper class which
converts results from the content providers cursor into Repo value objects,
there is no guarantee that certain attributes will be available on the
value object. E.g. if I load repos and only ask for "_ID" and "ADDRESS",
then it is meaningless to ask the resulting Repo object for its "VERSION"
(it wont be there), despite it being a perfectly legal attribute from
the Java compilers perspective.

Repo.id field has also been made private (sqlite is the only
entity should be able to set id's), and made id a long (sqlite stores
identifiers as longs rather than ints).
