geojson format breaks on CRS changes

GeoJSON CRS changes break GeoJSON format

[crschmidt]

Second patch has tests.

[crschmidt]

The reason this wasn't caught in testing is because the GeoJSON features being serialized didn't have layers. WIth no layers, there is in projection object, so the GeoJSON parser doesn't do any CRS anything. When you add a layer, it breaks. This patch fixes that, and adds tests to ensure it doesn't break again.

Tests pass for me in IE6 and FF

[crschmidt]

patch not dependant on test ordering

[crschmidt]

IE7 ran tests differently ordered on me, so this patch doesn't depend on ordering. rerunning tests in FF, IE6, IE7 now

[crschmidt]

Tests all passing in IE6, IE7, FF.

(In [4819]) The createCRSObject stuff never really worked. Unfortunately, the tests didn't catch it because they were all minimal unit tests -- so they never hooked up features to layers with projections. This fixes the createCRSObject function, including updated documentation, and includes tests for regression. (Pullup #1062)
