Adaptation of argument list by inserting () has been deprecated in 2.11, which linx without variables relied on.
This removes the apply method from Linx, but provides an equivalent syntax without the deprecations through implicits.

Most code should be source compatible with previous release, but if you relied on the apply(A) method being available for any Linx[A, X], you can get the same result by calling links(A).head instead
