Allow to lock column sorting in data browser

[mtrezza]

Problem

Currently the data browser allows to easily change the sorting of data by click on a column.
This is practical for small data sets, but can pose a problem for large data sets.
(Accidentally) clicking on a column of a collection with tens of millions of docs can trigger a collection scan, use up all the hardware resources and bring down the DB.

Solution

It should be possible to lock the current sorting / disable the sorting on click.
