openlayers/tests/Layer/test_WMS.html
crschmidt abe2a52c31 With a confirmation that Tim is happy considering this a review, I'm going to 
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)
