[FIX] mail, im_livechat: correctly displayed message date

Messages are required to be displayed in a smarter way: relative to the
current date, if it's a recent message, or absolute if not.  This
commits rework most of the date processing code to comply with these
requirements.

Messages were preprocessed each time a thread is rendered, which is
stupid.  It should be preprocessed only when the message is created.
This was a small problem because livechat does not use the chat manager,
so a simplified version of the preprocessing had to be done.
