Fixes #90.
Fixes #89.  We now have support for getting job creation, start, end, and execution hosts.  This is not done in a super efficient manner (there is a call to scontrol for each attribute), but it seems to work and we can optimize at a later date if needed.
Fix for #95 (environment variables in condor argument).
Merge branch 'devel' of github.com:saga-project/saga-python into devel
Add config for testing condor on OSG via the engage submit node.
Implement #33 (condor exit code) through condor_history.
Only use first line of output.
This test should just test for exit code, not for quoting :-)
typo
Fix garbage collection remnants in queuing adaptors, typo in http adaptor, variable initialization in pbs adaptor
