Look up keys that are independent of layout and state first,
followed by keys that are only mild variations in layouts.
This is more robust as there might be multiple physical keys
generating the same symbols, and Keysyms don't map directly to
Unicode in all cases.
At the same time switch over to using the modern, standardised
'code' field for lookup.
Use the more modern 'key' field, and remove some legacy fallbacks
that are no longer required. This also removes the "stall" mechanism
as it is not needed with current browsers.
This updates the tests to work with the new structure, and removes the
old `utils/run_from_console.js` files in favor of just using Karma
directly. The Karma debug page now displays the normal mocha HTML, so
we can use that instead of the HTML generation functionality of the old
test runner.
Note that PhantomJS does not work at the moment (PhantomJS 1.5 should
make it possible to test on PhantomJS again).
This commit moves all the input-related files from `core/`
to `core/input/`, and renames a couple as relevant
(input.js --> input/devices.js, keyboard.js --> input/util.js).
This commit restructures noVNC, splitting it into the core directory
and the app directory, with the former containing core noVNC parts,
and the latter containing parts specific to the application.
