Closes #152

@vildead I am not sure if we should index based on date. I remember we had exact date indexing very early on in DAISY and it results in a veery long list in the StartDate facet box of Project search page

@pinar - I see. That would be really long. But it seems the Date facet box is not there any more - just Start/End Year.
We can change the ordering Start date to Start year - then there will be no need for the date in index. Let me know if you agree.

If the newly prepared exact date index field will be used for sorting only then ignore my comments. I had assumed there would be a facet. Go ahead.

Yes, thats correct. The new index field is just for sorting :)
