Mail formatter rewrite

All mail-parsing and formatting code has been moved to em-format.
Parsing is handeled by EMailParser class, formatting by EMailFormatter.
Both classes have registry which hold extensions - simple classes
that do actual parsing and formatting. Each supported mime-type
has it's own parser and formatter extension class.
