Subject: [PATCH 1/2] CURA-5135 Easy version

This is the easy fix. When a plugin is downloading, the other plugins' download buttons are not possible to be clicked. This avoids having to write any new logic. It does detract a bit from the user experience though.

The complicated version requires re-writing a big part of the plugin browser code to enable the queueing of downloads and stuff. That's sort of how it "should" be but is a lot more work.
