RFR: 8015376 - Remove jnlp and applet files from the JDK samples

[Daniil Titov]

Please review changeset that reverses changes done in the team forest
(https://bugs.openjdk.java.net/browse/JDK-8015376 removal of applet demos).

JDK-8015376 changes were integrated in 8u-dev team forest only, so there
in nothing to reverse in JDK 9.

Both changesets will have to come through 8u-dev forest

Bug: https://bugs.openjdk.java.net/browse/JDK-8059136
8u40 webrev: http://cr.openjdk.java.net/~dtitov/8059136/webrev.00

Thanks!
