Open filemanager on new tab

[supbish]

Feature suggestion -- you know "openonstart?"

filemanager-openonstart | Automatically open the file tree when starting Micro | false

Take it to the next level:

filemanager-openontab | Automatically open the file tree when opening a new tab | false

This would open filemanager any time you hit Ctrl-T.

We could then hit Ctrl-T before opening a file from the tree when we want it in a tab instead of a split.

Maybe this would also satisfy #53, #47, #26

...maybe it could also "closeontab" when you Ctrl-Q out of the file you opened?

I've hacked very basic support for this into my copy of filemanager.lua:

function onAddTab(view)
	open_tree(view)
end

This can really only work if all trees share the same buffer, which they don't right now... but only the last tree opened appears to be functional anyway (whether you use this hack or the "tree" command after opening a new tab), so I guess you might as well have all open trees share the same buffer if possible.

You could just add another filemanger command like:

lua:filemanager.tree_in_tab

And then you can have one command to toggle the tree on the open tab and another to open it in a new tab
