- added ability to redirect user pages

- search for communities through Lemmyverse.net or for posts through search-lemmy.com directly from the popup or sidebar
- First feature pulled from LemmyTools! You now have the option to hide the Lemmy sidebar entirely (more LemmyTools features to come!)
- Replaced non-functional ‘subscribe’ button on foreign /communities pages to make them useful (only when no account is signed in, so not to replace something functional)
- Initial support for Alexandrite & Photon frontends. Test them here:
* Alexandrite: https://a.lemdro.id/c/lemdroid
* Photon: https://nu.lemdro.id/c/lemdroid
* New ‘communityNotFound’ button to account for alternate frontends: https://lemmy.ca/c/lemdroid@nu.lemdro.id
- Fix for generated link on CommunityNotFound pages
- Biggest change was behind the scenes: Completely refactored the code to move repetitive functions to a utils.js file. Should be a lot easier for people to collaborate and to maintain

- You can now customize the instance list to match which instances you actually use. This should be helpful for those that have accounts on different instances.
- Added a settings page so that you can turn off features that you don't want active
- Added buttons for helpful tools that let you explore Lemmy/Kbin communities (with lemmyverse.net), and search across Lemmy sites (with search-lemmy.com).
- Added a sidebar for those that prefer it (works on Firefox, Chrome & Opera; Edge doesn't have sidebars yet but the code is there)
- Fix for issues with the search trigger on the community not found page (thank-you to whqwert!)
- Various bugfixes, small theme changes, and improved wording

Changes:
- Added support for Kbin
- Fixed issue where button wouldn't load when navigating to a community within Lemmy (fix is only on Firefox version for now).
- (NEW) Right-click context menu on Lemmy/Kbin community links to let you open them directly. You can test them out here: https://lemmy.ca/post/1282303. This is also only on Firefox for now.
- (NEW) Information and buttons added to "Community Not Found" error pages to let you fetch the community or open it elsewhere.
- Updates to sidebar button to state the current selected instance and provide more detailed instructions as a dropdownList
- Refactored the code to remove more unnecessary permissions.
- Another pile of bugfixes, UI improvements, and better wording for instructions.
