Cleanup of client defaults structure
After the split of the client and server config files, default_image_path was left in client.rb.  This variable is now removed as well as default_base_path since it was the only other local variable for the defaults method.  If it is needed to pull out variables in the future for other reasons we can address it at that time.  Additionally, strings have been replaced with symbols for the hash keys.  The unnecessary return has also been removed.
Cleaning up circular 'require' reference
core/hanlon_global.rb requires core/policy.rb which in turn requires core/policy/base.rb
core/policy/base.rb does not need to require core/hanlon_global.rb
Removing references to legacy require 'project_hanlon'
project_hanlon.rb no longer exists
