New options object

New options object

Add a new options object. By default all user configuration items will be
set here. In short any program option that can be set by the user
will appear in this options object.

Also in this commit, I've removed a bunch of extra items that are not in
use by mtalk to avoid confusing users.

Program options work/linking with boost program options

To compile this now we require boost program options. The
relevant option has been added to SConstruct. There is no
checking that there is boost installed on the system yet
though.

There are 3 options, only one of which actually does something

1. --help -h
2. --version or -v
3. --local-port or -p
