cleaned up mounting code

mounts are no longer passed paths, instead the variables are used
directly from the cherrypy.config
localization removed as instance variable; referenced as cherrypy.config
attribute instead
sanitization added to misc.localization
added content-type headers to json responses

replaced instances of dumps() for preferred cherrypy.tools.json_out9)
which also sets content-type headers, in addition to jsonifying data
