[Featureserver] Minor bugs/requests in featureserver 1.09

[Kurt Schwehr]

Hi Christopher,

Since I'm looking at the code, I figured I'd contribute a little back to 
the project.   I've added a little big of a command line interface to the 
featureserver_http_server.py.  It's not much, but thought it might help. 
I was thinking that it might help people try out the package if they could 
specify the location of the cfg file.  This could be for either running 
multiple feature servers or having to place the cfg outside of etc 
(e.g. my case where this is required by the fink rules - 
/sw/etc/featureserver-py25/featureserver.cfg)

The comment section is epydoc format and if you aren't into that, just 
nuke that section.  I've included an example of what the epydoc html looks 
like.

The attached script output:

./featureserver_http_server.py -h
Usage: featureserver_http_server.py [options]

Options:
   --version             show program's version number and exit
   -h, --help            show this help message and exit
   -H HOST, --host=HOST  Which network name to use for serving [default:
                         localhost]
   -p PORT, --port=PORT  Which port number to use  [default: 8080]
   -v, --verbose         Make the program explain more of what it is doing
