The only reason it worked was because DB fetches calls to get$varname if
the dataobject has a variable with the specific name. However, it started
blurting out errors that the case must be correct (which would require
'geturl' to be the function name).
Since we probably want to replace DB sometime, we'll just override this
auto-fetching mechanism and use more explicitly defined functions.
The exception thrown from MediaFile will be caught and simply result in
no thumbnail at all right now. In the future we might use a catch-all
and have a "cannot generate preview"-icon or something.
VideoThumbnails requires php5-ffmpeg and php5-gd.
The parent class for our database objects, Managed_DataObject, has a
dynamically assigned class in staticGet which objects get put into,
leaving us with less code to do the same thing.
We will probably have to move away from the DB_DataObject 'staticGet'
call as it is nowadays deprecated.
Some minor database changes for file tables. Namely:
* Added a timestamp to all tables
* Added a filename column for local files
* Change some tables that had unnecessary auto-increment primary
keys when they had another unique column that should act as
the primary key
* Change engine from MyISAM to InnoDB for a couple of files.
Also, rebuilt the DB_DataObject files for all these tables.
