[TYPO3-mvc] RFC #7098: FlashMessages should support types

[Dennis Ahrens]

Hi list,

This is an SVN patch request.

Type: Feature

Bugtracker references:
http://forge.typo3.org/issues/7098

Problem:
A FlashMessage is a normal string without any further information 
descibing the message.

Solution:
FlashMessage becomes a class that holds further information describing 
the message :)

regards
Dennis
