Add a way to install/uninstall plugins via ui

[Silverdimond]

A copy of something like the visual studio VSIX installer will do on the installer side while the uninstaller could do the same

Maybe even a disable feature which just renames the dll files, but they (dll files) would have to be in a user accessible directory or require root privileges to disable/install/uninstall.
I am unsure how this would act with package managers.

Plugins should be managed by the package managers, on linux it's as simple as having multiple packages, one per plugin,
I've decided to not include a UI for this
