After shrinking the global example placeholder size, ones with
additional content within the demo area needed to be tweaked
individually, to prevent the other content from wrapping down or
extending off the side of the container.

The smaller size ensures that the example plots remain fully visible on
more of our most common visitor screen resolutions.

We don't want users to think the example is broken when they first load
it.

This prevents the Chicago example from showing up blank.  The
alternative is to define a callback, but that's messier.

This allows a page to have multiple placeholders, since we're no longer
tied to unique IDs.

Give any direct child of demo-containre the same style, so it can be
used for both #placeholder and #overview.

Added explicit border-spacing to compensate for global removal of
padding.  Flot should really take care of this itself; layout-critical
styles shouldn't depend on the user-agent defaults.

Slightly widened the page to account for the fact that most people have
widescreen monitors these days.  Also made text larger and more legible,
and created a nice 'clipping' effect for the placeholder.

To improve organization with the increasing number of examples, every
example page is now the index of its own subdirectory, which contains
all the files specific to that example.

Also fixed formatting and removed unused change to tickFormatter args.

It's useful to include the tickDecimals option in one of our examples,
so it's easier to test across versions.  The setting-options example is
the logical place to put it.

Linked the errorbars example to the examples index page, and cleaned up
both the example and documentation at the top of the plugin.
