Improvements of the 'performance' test program

[Nicklas Nordborg]

I will gather a few enhancements to the 'performance' test program under this ticket. Feel free to add more items to the list.

1. Names of raw bioassays should be 0-padded to make them sort correctly. Right now the sort order is: ...#1, ...#10, ...#11, ...., ....#2, .... and so on, which makes it hard to select a specific number of raw bioassays when creating a root bioassay set.
2. Names of data sets and jobs should follow a better scheme. For example, the name of a root bioassay set should include the number of raw bioassays.
3. The test program should only register job's, not execute them. This would allow us to control if the internal job queue should execute the job or a job agent.
