Added VT_API constant.  Bumped version for testing.
Modified API URI constants to use Uirusu::VT_API
Moved RESULT_FIELDS here for easier updates in the future.
(Hopefully) Added support for processing multiple results at once. Attempted streamlining of output options and results parsing.
Modified POST_URL to utilize Uirusu::VT_API
(Hopefully) Added file rescan support.
Moved RESULT_FIELDS here for easier updates.
Maybe this time I'll actually have RESULT_FIELDS in the file.
Removed commented out code blocks.
Removed the code to add the <results> </results> tags when XML output specified.  This is now handled in vtresult.rb.
Moved the prepending and appending of <results> </results> here instead of in application.rb
