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
This demo presentation is written entirely in Markdown, as provided
by the combination of the extras plugin, and extras/markdown/markdown.js
The idea for using Markdown instead of HTML came from users who felt that
sometimes when you just need to quickly toss together some slides, using
Markdown is faster than HTML. Same approach is also familiar to Hovercraft
users, where RST is converted to a traditional HTML based impress.js presentation.
Unlike Hovercraft, using Markdown.js allows you to write Markdown directly into
your html file that is the presentation. It is converted in the browser, and no
separate command line tool is necessary. As a result you can also mix and match:
some slides can be HTML (when needed) and some in Markdown.
