RFR [9] : get_source.sh should be more friendly to MQ

[Chris Hegarty]

Anyone using MQ for their daily development will know about this, 
forgetting to qpop before sync'ing up. It would be nice it get_source 
would pop and push patches ( only if you are using MQ ) automatically. 
If you do not have patch repos, then there is no change.
