Resize tag sidebar with the mouse

Good one, right now the sidebar width is limited to show only 12 character tags. If it's longer, it gets truncated to show 11 characters + "..." symbol.

As an alternative, sidebar width should be fit the longest tag. Um, I like this even more than mouse-resize :)

Well it is not exactly "limited". See FAQ in CN Help:
"How can I change the width of the tag sidebar?
    Change the app.mainframe.tagsidebar.width parameter in the cintanotes.settings file to the desired width in pixels."

And I like the autosize idea, added it as separate request: http://roadmap.cintanotes.com/feedback/9090-/
