Description

Add support for distribution lists (groups)

* src/oomhelp.cpp (get_recipient_addr_fallbacks):
Handle distributionb lists and plit into
(get_recipient_addr_entry_fallbacks_ex): New. Handle
the exchange stuff.
(try_resolve_group): Resolve distribution lists.
(get_oom_recipients): Check for distribution lists.
* src/oomhelp.h: Add some new defines.

This adds support for contact groups / distribution lists.
Not tested with exchange yet but it should work as the code
for the exchange fallbacks is still used.
