Support directories in path to :save
This adds new functionality to :save in the message view for specifying directories in the path. A new flag, -p, is also added to :save for automatically creating any directories in the path that do not exist. If the path ends in a / (e.g. "Downloads/mail/") or if the path is an existing directory, the part's file name is the filename from the mail header for the part. Otherwise, it uses the last element in the path as the filename (e.g. 'blah.jpg' is the filename if the path is 'Downloads/mail/blah.jpg')
