Updated CAF part 1 dialog

CAF part 1 dialog now includes info about HC document provided (if
applicable), as well as "faxed" as an option for how application was
received, and a new field for interview type (phone/office). All are
comboboxes.
Additional dialog changes

CAF 1 and CAF 3 were updated. Apparently the functionality to case note
the retro request was always in the script but no editbox was case
noting.

I removed the blip from CAF1, and updated CAF3's "HC begin date" to read
"retro request date". We'll pop it there.
Updated case note and dialog

Added previous dialogs to script, and updated the case note. As a recap:

Interview type (phone/in office/other)
HC document received (Req to apply/HC ER/other)
HC datestamp (date/text)
Retro request (date/text)
