This Pull Request contains a few modifications, please look over them because they will break current functionality of existing software if they're not accounted for.

- In order to use modules other than leads, I added an attribute to insert_records to specifiy the module used. 
- I've consulted with Zoho's API developers, the use of tickets are deprecated and if the &ticket= parameter is sent in a request it will cause a 4500 error. All that should be required now is an authtoken.
