Record all livecode executions

[anandology]

It is important to capture all the livecode executions for the following reasons:

1. execution is a marker of activity on the site and it could be used for tracking activity on the site
2. that gives us a sense of how easy or difficult the problems are, where are people getting stuck, identify if are getting stuck and offer help before they decide to drop etc.

That will also help us to write test cases to see what kind of errors people are making with each kind of problems.
