Create a Layer class to access the ArcGIS 9.3 Map Export service. Patch by

Jeff Adams, from Avencia. r=me. Tested with the default service, and several
other example map services from ESRI (like
http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/export).

Note that I don't believe this takes advantage of map caches; if we create a
seperate layer for that, we should probably create a Layer.ArcGIS. namespace.

(Closes #1749)
