package/dovecot: New package

[Thomas:
 - slightly adjust the prompt of options in the Config.in file
 - fix license: it's just LGPLv2.1, no exceptions. Parts of the code
   are under public domain, or under the MIT license, but the
   combination is under LGPLv2.1.
 - rewrap one comment in the .mk file.]

+	  Dovecot is an open source IMAP and POP3 email server for Linux/UNIX-
+	  like systems, written with security primarily in mind. Dovecot is an
+	  excellent choice for both small and large installations. It's fast,
+	  simple to set up, requires no special administration and it uses very
+	  little memory.
