This commit adds the missing shell script dependencies to the Readme and the Arch Linux PKGBUILD.
Also, for the Arch Linux PKGBUILD, the dependency array is moved into the
package() function. This is because
makepkg considers packages in the global
depends array as buildtime dependencies, too, whereas it does not provide any means to declare runtime-only dependencies. This is a commonly used "hack" to work around that limitation (see this).
Moreover, the PKGBUILD mistakenly installed
tl.pl, thus erasing the real
tl.pl; this is fixed now.
Finally, I was so keen to (slightly) revamp the
epfl-vpn scripts (for latter, the options are changed now, so backwards compatibility is broken there).
