Cleaning up comments/dialogs/functions

Just added comments, moved the dialog to the top of the script (as in
the newer ones), and modified a few random functions that had been
replaced with FUNCTIONS FILE functionality. Doing this and committing it
in advance of additional changes about to be made.
Added references to verif req form B

Added verif req form B to the case note as well as the success box at
the end. I also changed the case note from being sendkeys to the
write_new_line_in_case_note function. And I dropped references to "EV",
replaced with "employment verification". Clear language FTW.
Added changed TIKLing to be a checkbox option

A few changes came with this one:

1. Updated the dialog to make TIKLing an optional event, by adding a
checkbox. While I was up-in-there, I also changed the "is job already
known to agency" to be a checkbox (so that it won't default to "Yes"
anymore).
2. Updated script to reflect dialog above.
3. Set TIKL_check to default to "checked".
4. Updated references to job_known variable, to be job_known_check, and
removed "Yes" (replaced with "checked").
5. If create_JOBS_check is checked, it will now case note that the JOBS
panel was updated.
6. If TIKL_check is checked, it will case note that the TIKL was sent.
If it's unchecked, it won't case note it.
7. Script ends right after case note, if the TIKL_check is unchecked.
8. A pet peeve that I never fixed until now: now the TIKL says "if not
received and processED", note emphasis on previously missing -ed suffix.
