added java gc logging option

optimized command_start for xms
fixed issue with KeyError vs NoOptionError
java:java_debug = (bool) now creates GC logging
use localization filenames by default

all cherrypy mounts will automatically substitute in the localization to
index/login.
index.html and login.html appended with _en
cherrypy.notfound defaults to en so providing either login or index will
still serve both required pages (even if not translated)
