(svn r3214) -Feature: openttd.cfg can now set how many autosaves to keep before starting to overwrite old ones

Browse Source 
max_autosave_num in the config files sets the number of autosaves to keep (default 16)
	MAX_NUM_AUTOSAVES in Makefile.config sets the default value. 16 is used if no value is given
	this behaviour can still be overwritten by keep_all_autosave (openttd.config setting)
	Note: this is a requested behaviour for PDA ports, since they got limited storage space
