Add urlencoded and doubleurlencoded formats to the view widget

First pass at a saver for IE10 and above

It's not great, sadly. Clicking save in the browser pulls up an
unobtrusive bar at the bottom of the browser window where you can click

Docs update
Removed inadvertent alert()
Fix $tw.utils.hasClass() to work even if the element doesn't have a className property
Improve popup dismissal

Now we ignore clicks if they come from an element that has an ancestor
with the class `tw-popup`
Update the reveal widget to set the tw-popup class
Update the tiddler info panel to use the new tw-popup class

This fixes the problem with the inability to click on items within the
tiddler info panel (including the static URL)
