Updated the record command to allow revent recordings to be made.
They can be performed in 3 ways; the default is a standard recording
as in WA2, it can start a specified package before starting the
recording or a workload can be specified which launches the workload
and prompts the user to record each stage, naming and storing the recordings
appropriately.
Changing the way target descriptions work from a static mapping to
something that is dynamically generated and is extensible via plugins.
Also moving core target implementation stuff under "framework".
