Added script for setting up my manual testing vospace to gitignore.
Flush output after each accepted source when processing candidates.
Merge branch 'master' into vos_flush_cands
When a file is finished in VOSpace, the value of the 'done property' is now 
the operator's username (instead of just a static flag value).
By default the VOSpace progress manager will no longer record partial
progress in a file.
Added sync_enabled flag to SyncingVOFile constructor.  The application
now has syncing turned off, meaning the user must manually copy their
results to VOSpace after finishing.
The application now has the notion of separate input and output 
contexts.  Added -o/--output option to validate.py so that you can change
where output files get written.

Merge pull request #107 from drusk/vos_flush_cands

More local flushing, less VOSpace syncing
