Panorama Tab Groups por projectdelphai

Hopefully the 0.8.10 release didn't mess up too many people. I released a quick 0.8.11 patch and it was messy but it should have reverted the commit that messed up 0.8.10. Please let me know if it didn't.

Welcome back after the holidays! As usual, sorry for the quietness but here's finally a new release. There's a lot of new exciting features such as tiling, search functionality and small QoL changes. I've been doing a lot of side-projects due to a new job to keep learning. I have my new dev environment up and running so you should start seeing more work from me soon! I'm hoping to get a new computer near the end of the month to replace my old dev server, but hopefully I can pump out some quality work before I go dark for that. Sorry for the wait and enjoy the following news!

New Features/Changes
==================
1. Added Tiling! The icons will probably get reworked in the future, but you can now (at the view page) select whether you want freeform view to move groups around as you want or tiling to automatically evenly split all the groups.
1. Basic search functionality is now here! Type the name of the open tab you want to find in the search bar in the view page and that tab should now be selected and highlighted in blue.
1. If you click on a group in the background, it'll now raise to the foreground (thanks to @crass )
1. Restoring from old extensions should look a little nicer now (thanks to @crass )
1. You can now move tab groups by selecting any part of the group, not just the header. Mouse icons should reflect this now as well.
1. There is a reset button now but it isn't implemented yet. Hoping to have it finished by next release.
1. Title of tab groups shows up when you hover the icon, the number of groups is now displayed on the icon as well.
1. Added new translations

Bug fixes/Backend work
==================
1. David Gurk reworked a lot of how the shortcuts are handled and coded and helped out a bunch. Thanks!
1. David removed urls from the tab group tab titles which was causing issues with PTG and rendering the view/tabs properly. Should reduce a bunch of the blank screen issues.
1. Fixed bug which broke the backup utility
1. Groups are created properly on new windows
1. Removed internal debugging console logs, added comments.

Known Bugs/Issues
==================
1. Group IDs always increment and never decrement after closing a group so if you've been using PTG for a while, I'm sure your IDs will be very high. I'll be fixing that soon, ~should be an easy fix.~ It wasn't as easy as it looked. Will still be looking into this.
1. I'm sure many translations broke with the new plural rules. Please take a look at the bottom of [this page](https://github.com/projectdelphai/panorama-tab-groups/blob/master/CONTRIBUTION.md#translations) to learn how to add plural rules to fix any broken translations.

Thanks for waiting and supporting this project :) As always, suggestions are welcome [here](https://github.com/projectdelphai/panorama-tab-groups/issues). We're especially looking for translations so please help if you can! If you're not sure how exactly to submit a pull request, you can just translate every message line [here](https://github.com/projectdelphai/panorama-tab-groups/blob/master/src/_locales/en/messages.json) and drop it in an issue and I'll put it in the code.
