Check encode time for mandatory resolutions.

Currently it there is no criteria for failing or passing depending on the encode time. It will print out the average, max and min, also an error message will be printed out as reportInfo (do not want to fail the test) when no stats can be gathered. 

Since I do know any acceptable encode time value ranges I think this is sufficient for now.
The proper way to reduce gets and others is to compile the js and minify it...
Then we can simply merge all js files into a single blob.

For bigger applications there is a need to keep modules separate to avoid the final blob to be big.. but this project is very far from that sort of optimizations.
