DevTools: NOOP if outline dialog is not available for the content type

DevTools: NOOP if outline dialog is not available for the content type

Currently hitting Ctrl-Shift-O on any typescript/python/C++ file in
DevTools will result in opened bookmarks tab (at least on linux).
Almost all the time, if user is editing code in Sources Panel and hitting
Ctrl-Shift-O, he expects outline dialog to be shown.

As we are not capable of supporting all the fancy file formats yet, the patch
suggests swallowing Ctrl-Shift-O for those content types that we do not support.

default:

seems more readable. It's also worth adding a comment next to this "return"

Done.

lgtm

We should implement this through a ShortcutRegistry.
Let's land this one for now though.
