Iterate on interfaces, tokens, and UI.

• The IDebugger interface should only need to expose a mode: IDebugger.Mode and a session: IDebugger.ISession
• The sidebar plugin should be removed.
• The main debugger plugin should mount the Debugger#sidebar in the right hand side if mode is set to condensed, otherwise it should mount it in the main area.
• The Debugger extends BoxPanel class should have an attribute called editors that is a TabPanel of read-only text editors that allow users to add breakpoints.

There are some TODO notes in this PR that also give some guidance. In general, the patterns in @jupyterlab/completer-extension and @jupyterlab/inspector-extension are helpful here. They are slightly different from each other, but both very close to what we want, here.

cc: @KsavinN @LeeTZ @jtpio This is as far as I got. I spent more time refactoring the actual plugin plumbing instead of the tab panel bit, unfortunately. I hope this is enough to go on for you!

@jtpio @JohanMabille Should we merge this PR? I pick up this branch and done all task without that last one "The Debugger extends BoxPanel class should have an attribute called editors that is a TabPanel of read-only text editors that allow users to add breakpoints.".

OK then let's open a PR here on this repo against master since your branch seems to be based on this one.
