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.
