Queue execution

Created by: meguiraun

Another PR... This one is a bit special...

It aims the milestone Jan16. Basically client-server stuff, the hwobj mockups do not fully work (a pr will come soon) but the client-server is functional. For testing:

• add some samples and methods to the queue
• if you want to execute a single sample:
  • Since the ho_obj fails, we have a patch for emulation random results and displaying colors in the queue accordingly, uncomment line 260 from routes.Queue.py
  • run the play button next to it (a sequence of ~10 s will happens)
• if you want to run the whole queue
  • click the run button at the bottom of the queue
  • and the centring method will start, and it will wait for the click position and the centring accept
    • curl -i -X PUT -H 'Content-Type: application/json' -d '{"clickPos":{"x":"123", "y":"456"}}' 'http:/server:8085/mxcube/api/v0.1/sampleview/centring/click'
    • `curl -i -X PUT 'http://server:8085/mxcube/api/v0.1/sampleview/centring/accept'``

You might need to repeat the last step of you have several samples/ methods. In the system log view you should see messages from the hw_obj

We are moving to the sample view so those two curl steps will not be needed, also, we are fixing the hw_obj mockups (autoloop, and some missing messages).

I know that it is not fully functional as it is (although it works, at least for us), due to the relationship with the mockups and the sampleview. We hope to enhance the missing issues in the next days
