Add Content-ID header if cid is specified.

Message.add_attachment takes an optional cid keyword argument. However,
  if it is given, it's not used to actually set a Content-ID header.
Update tests to check for Content-ID header.

Change string formatting syntax for style purposes.
Handle case when cid isn't specified at all.
Merged pull request #4 from emtrane/master

Closes #3
Bumped to 0.1.1
Don't include a Content-Disposition header when cid is provided

Providing both a Content-ID header and Content-Disposition header
with type 'attachment' confused some email clients. If no
Content-Disposition header is given, it defaults to 'inline'
which is what is desired when using cids.
