Sherpa Prototype

- get rid of page_initialize non sense by merging it with the document ready JQuery function
- start migration to unobtrusive JS programming techniques; e.g. global variables / global functions
- break down edit.js into files to host the views for headers, programs & tests
- add a new tab to host the tests results which are still rendered by renderEvaluatedTests in edit.js until it's moved into the model parts of the program. The "tests" tab is using a partial version of this function which does not evaluate the program. Trying to keep edit separate from run / get tests results so it might be easier later on to log each separate run attempts; this will most likely evolve quickly
