* Plugin callsigns, filechangehandler thread bug fix, plugin file perms - Plugins are now assigned a callsign (a random string), which they use for all internal identification, like resource fetching and method calls. This is to ensure that plugins only access their own resources and methods. - Made FileChangeHandler send off events to a queue, that is then consumed by the Loader, instead of calling import_plugin on its own, since that caused weird issues with the event loop and the thread watchdog is using. - Plugins are now owned by root and have read-only permissions. This is handled automatically. * Improved general look and feel of plugin tab * Make all plugin entries have the same padding between them * Make "No plugins installed" text look the same as "No new notifications" Co-authored-by: WerWolv <werwolv98@gmail.com>
