UPDATE: replace subclassing with a DataExtension, add has_many warning

I replaced the subclassing example by one using a DataExtension. This
is the preferred way to add extra functionality to the Image class. You
can now add any existing image from the assets section instead of only
those belonging to the subclass.

Added a warning not to use has_many relations, because the UploadField
doesn't fully support them.

BUG Fixing "+" characters being replaced with whitespace

SS_HTMLValue::getContent() uses urldecode() on the content returned
by saveHTML() -- this was done to fix encoded HTML entities like
square brackets, which are used by shortcodes. Unfortunately, this
also removes valid characters like "+" from the content.

This fixes it so square bracket entities are decoded *only*, and
leaves everything else as-is.
