Allow the default order of Browse References branch list to be changed

What steps will reproduce the problem?

1. Open Browse References window
2. Click on a column header to change the ordering
3. Close the window and reopen
4. Ordering has reverted to Branch Name asc.

What is the expected output? What do you see instead?

It would be helpful if there was a way of setting the default order, so that I don't have to manually reorder every time I open the window.

For example, this could be done by holding down Ctrl while closing the window (as per Windows Explorer behaviour)

What version of TortoiseGit and Git are you using? On what operating system?

TortoiseGit v1.8.16 Windows 10
