Get started help

Wrote a perl script to assist with capturing and sorting portals from the Intel page.  This could probably be ported into the java app... but perl is my go-to language for quick stuff.

Updated the README with some useful information for getting started.

Moved authcookie / locations files to a .example extension, and added those files to .gitignore.  That way personal cookies & locations don't mix into the repo if other developers come in.
