Order the runs according to type

Currently the script mixes cosmic and collision runs, which makes it difficult to read the resulting elogs.
See e.g. http://cmsonline.cern.ch/cms-elog/1057885

Could we order the runs according to their types? First we would have collision runs and only after that all cosmic runs.

Start by locating the Python script that mixes runs when producing the resulting elogs, using the linked elog as an example of the current ordering. Trace how each run's type is identified and verify the output so collision runs appear before cosmic runs.
