Spherical mercator example now makes use of this, displaying coordinates
in lon/lat instead of meters, and permalink/argparser now work in lon/lat
as well. this functionality will make using SphericalMercator easier for
a number of applications.

externalProjection properties. These allow for the reprojection of data --
OpenLayers users with SphericalMercator get this built in for EPSG:900913, and
other users can use the external proj4js library available from MapBuilder SVN
to add support for any number of projections. This means that featres can be,
for example, transformed from a KML doc in 4326 to Spherical Mercator before
being added to a layer, making using SphericalMercator slightly more enticing.

this change, the Format.XML test passes in Opera.

and the Y transforms just make working with the SVG directly -- for example,
with people modifying it to support text -- more difficult than it should be.

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!

events -- this means that if an image fails to load, it will still trigger
a loadend event, and the layer will eventually be in a state where it is no
longer waiting to load. Thanks to Andreas for the investigation! (Closes#842)

the SphericalMercator mixin register two transformations to/from EPSG:900913,
EPSG:4326. Thanks to Tim for the feedback and review. (Closes#1210)
This allows us to transform points to/from SphericalMercator
without proj4js support -- and if other projects need similar functionality,
they can write their own custom transformation functions rather than
modifying proj4js to support some custom projection.

go ahead and commit this (relatively lighttweight) patch to the code so that
the projection library base API is there, even though for the most part, it's
not usable yet. This changes map.projection from being a string to being a
class, with a projCode on it. (Closes#1035)
