Sort by columns in orders list table

[bjarnef]

Is your feature request related to a problem? Please describe.
At the moment is isn't possible to sort the columns in orders list table by clicking column header. It would be great to be able to do so.

Describe the solution you'd like
Clicking on column header should sort the column in ascending/descending order (typical visualized via a up/down caret icon next to the column header name). By default it could sort by as text, but it would be great if it also could specify column datatype, e.g. text, numeric (int), decimal, date/datetime.

This is related to https://github.com/vendrhub/vendr/issues/80 but I see this as a seperate feature.

Just a note that as part of 1.5.0 our custom table directive does now support sorting functionality, however this will need implementing for the orders table specifically as we've made it off by default.
