[Improvement] Improve view of existing data links

Hallo,

To get a better overview and findability of the datalinks, I suggest the following:

Insert a scrollbar at the top
Change column sorting to: o 1st column: Device short name and serial number in brackets o 2nd column: Measured quantity o 3rd column: Begin date o 4th column: End date o 5th column: offset o 6th column: data stream o 7th column: license o other...column:all others
default pages: all or minimum 50
open each datalink tab by clicking in the field and not only the arrow
