add new attribute side_name= in [side]

We cannot call it name becasue thats already used by the unti that is
generated from the side tag.

if given (nonempty), side_name= will be used instead of current_player
in some dialogs (new turn dialog, statistics).

In [scenario] side_name= defaults to name= while in [multiplayer]
side_name= defaults to empty (so that current_player is used in those
dialogs by default).

This specially fixes http://gna.org/bugs/?24226 while still giving wml
authors in mp and in sp the option to use the real players name in those
dialogs.
