Deactivated javascript until #105, #130 fixed.

Problem:
When the “start date” is changed the “end date” is automatically recalculated (based on the event duration).
This is just working if the “calendar widget” is used.
If the “select element” is used to change the end date, this feature will not work properly anymore (the end date will be miscalculated)

Details:
The end datum is calculated with the values stored in the “calendar widget”:
var start_date = $("input[name$='-calendar']", jq_start).data().dateinput.getValue();
But if the user has changed the date trough the “select element” before, this value is not “up to date”.

Propose:
I propose to deactivate this “feature” until we didn’t found a solution (The solution is not as easy as it seems).
