Patch to add support for attachments flag in TnyCamelMsgHeader

[Jose Dapena Paz <jdapena igalia com>]

	Hi,

	Just another small patch. This adds support for setting the attachments
flag in the TnyCamelMsgHeader (the TnyHeader used for newly created
TnyMsg).

	It's very similar to the previously sent patch to add support for
priority flags.
