mmcli: added --messaging-create-sms-with-text option

Added a --messaging-create-sms-with-text command line option that works similar to --messaging-create-sms-with-data, except that it uses the content of the file as the message text instead of data.

This allows creating mesasges containing both double and single quotes, which was not possible with the existing `--messaging-create-sms' command line option.
