Add worker to form

[gingerchew]

adds worker into the form object instead of into an array in the global scope

goal here is to keep the global scope completely clean if at all possible, exposing debug methods elsewhere

Testing needed on Firefox:
Bug happens as follows -

• Worker is created
• Worker begins verification process
• Before verification can be completed, the Worker is cleaned up by the Garbage Collector

Confirmed working on Chrome

Testing:

• Test each page inside of test folder on Firefox
• Test each page inside of test folder on Safari
• Test each page inside of test folder on Safari iOS
