wizard: rename incoming to source

Rename stuff in preparation of support for other protocols. Match the
terminology from accounts.conf.

This patch is more or less the result of the following command (with
some manual tweaks and cleanups):

  sed -i -r -e 's/_INCOMING/_SOURCE/g' \
            -e 's/IMAP_//g' \
            -e 's/SMTP_//g' \
            -e 's/([\.[:space:]])imap/\1source/g' \
            -e 's/([\.[:space:]])smtp/\1outgoing/g' \
         widgets/account-wizard.go
