w3m-load.el byte compile

[Kevin Ryde <user42@xxxxxxxxxx>]

This is an idea to byte compile w3m-load.el, so that its docstrings are
not loaded into memory unless or until they're viewed (which may be
never).

I suspect generate-file-autoloads puts no-byte-compile for the benefit
of emacs' own loaddefs which are dumped and therefore don't need byte
compiling.  For everyone else byte compiling saves some memory on medium
to large docstrings.

	* w3mhack.el (w3mhack-module-list): Remove w3mhack-load-file from the
	modules not to be byte compiled, so that it is byte compiled.
	(w3mhack-generate-load-file): Remove no-byte-compile from w3m-load.el.
