Scope and purpose

While working on upgrading jquery (due to security warnings, #2291), I found that jquery.tinysort had been updated to no longer have a jQuery dependency at all. As such, this PR adds the new standalone tinysort dependency.

The library was only used in the multiple_select plugin, which in turn was only used in info_netboxgroup.js.

How to test

1. Search for a device group, and open it in edit mode. E.g. /search/devicegroup/ACCESS/edit/
2. Select options in "Devices not in group", and check that they appear in sorted (alphabetical) order in "Devices in group".
3. Select options in "Devices in group", and verify that they disappear from the list and appear in sorted (alphabetical) order in "Devices not in group".
