Adds the capability for the HandBrake and Bluray source plugins to look
for sources in multiple directories using the new features of the config
class to support string lists.
The config class now supports a type column in the database which
specifies how the value should be interpreted. The class defines a
number of scalar types, which are returned without transformation. A
string list type is also defined, which splits the value into an array
based on newlines.
Also added phpdoc comments to all class constants, members and methods.
The column values parameter to RippingCluster_Database::selectAssoc()
now accepts an array of columns instead of a single value. If a scalar
is provided, the value is returned as a simple associative array; if an
array is provided, the full list of columns requested is returned as a
nested associative array.
Moved common default init/name methods to a base class, common to all
plugin types.
Added phpdoc comments to various plugin methods.
Updated HandBrake plugins to reflect core changes.
Added link to jobs page to fix any issues caused by non-synchronised
time between webserver/worker machine leaving jobs permanently in the
running state.
Prevented the insertion of new status records unless the state is
actually being changed.
Made the HandBrake worker process write the status complete message
instead of the run-jobs dispatched, in case it crashes.
A job may remain in the database after the source dir has been deleted.
The source object has been changed to permit construction even if the
source it represents doesn't exist, but will throw an exception if any
requests are made of the object.
The Perl version of gearman doesn't support passing the unique value to
the worker, so the job id is now passed in the workload request.
Also fixed a bug to ensure changes to job status are visible
immediately, rather than only on the next page load.
