Don't always rebuild on "make" (in the phony "all" target), but
introduce a real file target dist/index.js and its requisites. This gets
rid of the "install-only" target, which is very non-standard and would
not on an unbuilt tree anyway.
Also add a "devel-install" target that does the usual symlinking of the
built source tree into ~/.local/share/cockpit.
Closes#17
This makes sure we always include all files in the repository when
disting.
Obsoletes webpack-with-stats, which had a bug anyway: it wasn't
reporting jslint errors.
This moves us one step closer to a normal source package. The sources
are now unpacked and we run "make install". We still don't build
since we don't have all the necessary tools.
Also, most importantly, the source tarball now includes our actual
sources in addition to the prebuilt binaries.
