Everything so far

`method-list` (for adding breakpoints) isn't ready yet because `core-selector`  is buggy.
The plan is to put `method-list` and `object-tree` on the right side in separate tabs. But `paper-tabs` was  not being compliant with `vulanize`, so that's not done yet.

Requires `O.o()` to work.

Thank you
Right :) Sorry, I should have been more clear.
For historical context, it comes from sed: http://en.wikipedia.org/wiki/Sed#Substitution_command but it's also used in vi[m] and Perl (and probably other places too).
