crschmidt 995ef95dba Pullup changes to trunk for RC2. Includes drag-fires click changes
(Closes #982), comment/documentation/requires changes (Closes #983, #993, #988),
Fixing post support in proxy.cgi (Closes #991), baseLayer zoom level change 
(Closes #990), typo in Layer.Image.setURL (Closes #985), and a fix or the
Layer.Google bug caused by Google's changing internals (#994). RC2, here we 
come.
