Subject: Allowing static files to be served directly from a directory
 specified in the config.

Added a handler to svc.go:Start() to serve /static/
Added default value in conf.go for "StaticFilesDirectory" in the
config file.
Read the value of StaticFilesDirectory in config to the config
global in conf.go
