Cleaned up formatting of VoteSmart class.

The major change here is that you can no longer query directly from the constructor. The constructor now takes in 2 parameters:

1.) the output type, with a default of 'XML'
2.) the location in the global $_ENV array where to check for the API token supplied by VoteSmart is stored, with a default of 'VOTESMART_API_KEY'

You can also set these directly using the methods setOutputType(), setEnvKey() and setApiToken().
