provide an alternative to using `Alt-D`

[sigmundch]

I have a custom window manager that captures Alt-D and I haven't figured out how to bypass it. It would be helpful to provide some alternative to launch the Dart DevTools in some other way.

Some ideas:

• add a flag to launch it preemtively (--debug --launch-devtools)
• add a flag to override the shortcut (--debug --devtools-shortcut=Ctrl-Q 😉 )

Probably the easiest thing tho do is just create a global function on the page that can launch devtools. That gives a more generic hook for frameworks or users, so you can create a bookmarklet that launches devtools and frameworks could create custom development widgets that launch it.

• add a flag to launch it preemtively (--debug --launch-devtools)

We could consider something like this, but we already have a pretty complex handshake going on in terms of how we start the app and things, and it might end up creating a race condition as well.

• add a flag to override the shortcut (--debug --devtools-shortcut=Ctrl-Q wink )

I really don't want to try and parse arbitrary keys and convert that into a command haha.
