* generic/tclIOUtil.c (TclLoadFile):

	* generic/tclInt.h:
	* unix/tcl.m4:
	* unix/tclLoadDyld.c: added support for [load]ing .bundle binaries in
	addition to .dylib's: .bundle's can be [unload]ed (unlike .dylib's),
	and can be [load]ed from memory, e.g. directly from VFS without
	needing to be written out to a temporary location first. [Bug 1202209]
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59
