0.8.1 - Refined auto-installer, fixed node keymap
I believe that I now have a 2-3 click install process that will work for people whether they already have the community addons pre-installed or not.
The new install process will be updated in the README, but the gist is:
Download and install BLUI.zip like usual.
Then, after opening the BLUI template, navigate to the Scripting tab and click Run Script.
The setup script will automatically download, install and activate Mr Mannequin's Tools, Blender for Unreal, TexTools, RightMouseNavigation, ModifierStackManager, and CommentBox. It should not overwrite your existing installations, if you already have the addons, and they should all be activated and ready for use without prompting upon the completion of the script.
