Urs Liska 032376efad utf8: Add imap4_utf_7 codec
Add code to reencode IMAP folder names to regular utf-8.
This starts an implementation that will add a new config option
`utf8foldernames` on account level which will fix #299 and on the
long run replace the current `decodefoldernames` option.

This commit introduces code to register an `imap4_utf_7` codec
on which two-way conversion methods will later be built.
