[datatables] should be upgraded to current version

[krabina]

There are several issues regarding datatables reported here. However, the code indicates that SRF is using the version

SemanticResultFormats/formats/datatables/resources/ext.srf.formats.datatables.js

Line 7 in 5d93c63

* @version 0.2.5

0.2.5, when datatables.net is in version 1.12
So I guess the first task would be to upgrade datatables and then see what problems remain.

This was fixed with #730, thus closing.
