Add the ability to group tabs by tagging them about vieb HOT 1 OPEN

As you note, separate windows are supported fine if they use a separate datafolder (see :h datafolder). You can also supply --unsafe-multiwin=true, though this does mean that localstorage and cookies are likely to corrupt, as Chromium cannot handle multiple instances using the same store for this at the (exact) same time.

There are already container tabs in Vieb, which share their data only with tabs of the same container name. You can find help on this at :h containernames, :h containercolors and :h containernewtab among others. The color setting can even change the tab color based on the container name.

Given that containers are already there, I would suggest to expand the container system with extra commands that let you hide/show them in bulk based on title, as well as closing them by container name. I will think of suitable names for this, but ideas are also welcome. I am not a fan of using tags, as in the future bookmarks are bound to be using a tagging system too, so I would prefer to name this container labeling system differently.
