non-semantic changes to configure.ac to tidy up --help output, show default settings clearly, update TODO (hah!) clean up and rename QUICK-INSTALL as BUILDING_FOR_LINUX_2.4_KERNEL since that is all it really is

Specific Instructions for a 2.4 Linux kernel
--------------------------------------------
Quick Install Guide
---------------------
Before using JACK in realtime mode with a 2.4 kernel, you may
need or want to take the following steps. A better choice is
to use a 2.6 kernel.
1) in /usr/src/linux/include/linux/capability.h find these lines

3) if you're using a journalling filesystem, mount some directory with
-t tmpfs and tell configure about it with --with-default-tmpdir
-t tmpfs and use this with JACK's configure step as the
argument to --with-default-tmpdir.
4) configure with --enable-optimize --enable-capabilities and
--with-default-tmpdir=/where/ever
4) use --enable-capabilities with JACK's configure step
5) make
6) as root, do
make install
