Do not kill drawers in entry text

Style flags, such as "habit" are stored in the property drawer.
Therefore, don't kill the property drawer from the note / entry text.
Instead, excise the members of org-toodledo-property-names that
exist in the property drawer when returning entry text.
Set repeat even if only SCHEDULED/start repeats

Previously, only the repeat set on the DEADLINE was transferred to
Toodledo.  Now, a SCHEDULED repeat can also be transferred.  Toodledo
supports only one repeat so a repeat on DEADLINE has higher priority.
