Changed the onclick handler to trigger the impress:console:open event
and not use the impressConsole() global function any more. The latter
is considered deprecated now that impressConsole is integrated into
impress.js itself.
Also catch some errors that appear in event handlers when the target
for the click event was immediately removed from DOM.
Fixes#651
Press 'P' to show a speaker console in a separate window.
Supports:
- Navigation controls
- This slide and next slide preview screens
- Speaker notes
- Clock and timer
Also applies this patch, which makes impressConsole.js follow the new
impress.js plugin standard: regebro/impress-console#22
Note: As impressConsole is now a plugin, it is included by default. You
no longer need to include it with a separate <script> tag. Nor do you
need to call its init() method.
