feat:
* Added toggle for automatic tab group open/collapse

feat:
* Can now ask the group tab to prompt you before it gets closed, so you don't accidentally lose some data

fix:
* Reopened tab groups should show up in the context menu again

fix:
* Can no longer navigate away from a group tab
* Group will now open or close properly when state is changed due to a closing tab
* For example: Closing the last tab in a group will spit you out of the group
* For example: Closing the last ungrouped tab in a window will now open the remaining group

feat:
* Can upload a custom group icon

fix:
* Tab restoration now notifies you that the tab had to be restored

feat:
* Allow you to set group icon color

fix:
* Recreate missing group tabs on plugin start to try and mitigate the "Whoops all my tabs are hidden" bug
** This might reset your other settings ("Keep tabs opened in the group within the group", for example)
* Separate incognito and non-incognito groups
* Don't break everything if you disable/enable the plugin
* Restore group status on tab/window reopen, if possible
** If there is a new group with the same name, it can't be restored

* Clear tab data on plugin reinstall

* Rewrote from ground up to be more maintainable
* Updated group tab interface
* Probably fixed some bugs
* Possibly introduced some bugs (I couldn't find any, but that's what makes them bugs I guess)

Unfortunately, this new version seems to have broken backwards compatibility with old, already existing groups. It shouldn't be bloodier than just remaking the groups, but still, I apologize.
