Jesse Smith <jessefrgsmith@yahoo.ca> -> 5.3
	- Made the situation where FILE_AUTH more clear, advised
          against it. Added warning about making sure password
          file is not readable by another other than the admin.
	- Updated Makefile.in to use more fine-grained dependency
	  checks. Should speed up compiling when just one
	  source file has been altered.
	  New Makefile.in provided by Vemake.
	- Fixed out of bounds memory read when fetching options.
