#3058: Use correct maxResolution for Web Mercator

 Priority:  minor     |   Milestone:  2.11 Release

 In all our layer types that pre-configure the maxResolution for Spherical
 Mercator, we use 156543.0339. The
 [http://wiki.osgeo.org/wiki/WMS_Tiling_Client_Recommendation WMS Tiling
 Client Recommendation], however, defines a maxResolution of
 156543.03390625 (20037508.34 / 128).

 With our current maxResolution settings, when working with layers
 configured from a WMS-C GetCapabilities doc, which advertises the highest
 resolution as 156543.03390625, this may result in layers being out of
 range at the highest resolution.
