Add missing records

Hello,
I just added basic support for some missing SureTalk Records, and their related namespaces:
- [TimeBill](https://system.netsuite.com/help/helpcenter/en_US/Output/Help/SuiteCloudCustomizationScriptingWebServices/SuiteTalkWebServices/TimeBillTrackTime.html)
- [JobStatus](https://system.netsuite.com/help/helpcenter/en_US/Output/Help/SuiteCloudCustomizationScriptingWebServices/SuiteTalkWebServices/ProjectStatusJobStatus.html)
- [ProjectTask](https://system.netsuite.com/help/helpcenter/en_US/Output/Help/SuiteCloudCustomizationScriptingWebServices/SuiteTalkWebServices/Tasks.html)
- [Employee](https://system.netsuite.com/help/helpcenter/en_US/Output/Help/SuiteCloudCustomizationScriptingWebServices/SuiteTalkWebServices/Employee.html)

Give me some time to add specs...
Thanks a lot!
