to do:

• create a snailsnap email address (e.g. googlemail)
• add command line paramerters to specify all needed email settings (server, our mail address, password) - don't commit them into the repo!
• add a sendimage function to mailclient, see sendtext for reference
• send the output image somewhere (for now, you could specify another command line parameter for the target mail address)
