Add support for the extremely awesomely super-comprehensive rule based styling
that Andreas has been working so hard on. I think this is the single most awesome commit I've ever had the pleasure of committing. The results of this commit are described on http://trac.openlayers.org/wiki/Styles: essentially, this makes it possible to style features in all kinds of fun ways based on rules, and will also form the underlying basis for #533. Things this patch adds: * OL.Rule classes. These classes allow you to do tests against the propertie of a feature, and set a style based on these properties -- so you can compare the 'speedlimit' property of a line, and test if it is > 60, and if it is greater than 60, render it in a different color. You can also test combinations of rules using the OL.Rule.Logical class, and test featureids with the FeatureID class. * OL.Style class: The OL.Style class lets you wrap up Rules into styles that can be used with drawFeature to draw the feature in the selected style. * OL.Layer.Vector.drawFeature will check if the given style is an OL.Style object, and if so, it will draw the feature accordingly. examples/georss-flickr.html shows usage of these classes. Many, many thanks go to Andreas for all his hard work on this: this code really is very pretty, and includes unit tests for all the classes (and we know that I am a big fan of tests.) Three cheers for Andreas: Hip hip, hooray! hip hip, hooray! hip hip, hooray! git-svn-id: http://svn.openlayers.org/trunk/openlayers@5429 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf

<p>The displayed GeoRSS feed has a <tt><media:thumbnail/></tt> property for each item. An extended <tt>createFeatureFromItem()</tt> function is used to add this attribute to the attributes hash of each feature read in by <tt>OpenLayers.Format.GeoRSS</tt>. The example is configured with a style to render each item with its thumbnail image. Also, to show how rules work, we defined a rule that if the title of an rss item contains "powder", it will be rendered larger than the others.</p>
