More code cleanup and put loops back in

Some more code cleanup for wrongly named variables and variables not formatted in camel case.

Put the loops back in around the login and get token request as it has been found that on certain VTiger API's this loop is needed. As part of this your config file needs "max_retries' => 10" added to it, also an error check has been added that will throw and error if the max retires is reached with no response.
