Subject: [PATCH] Improved metadata handling

Two main points: Firstly, there is no longer a random mapping between
app['key'] and a corresponding field in the metadata file - the key and
field are now the same. Secondly, more information (including comments)
is retrieved from the metadata, to facilitate being able to re-write it
which is necessary for various support utilities.
