Subject: [PATCH] JBDS-4132 Could not load nodeJSInstall:
 node-v0.10.22-linux-x86_64

The destination directory for unpacking the Node.js runtime is changed
from <tern.eclipse.ide.server.nodejs.embed.<os<.distribution>>.<platform>>/<node.js rintime zip-filename>
to <User's workspace>/.metadata/.plugins/<tern.eclipse.ide.server.nodejs.embed.<os<.distribution>>.<platform>>/<node.js rintime zip-filename>
in order to prevent the attempts to extract the runtime zip-archive into the directories with
restricted access rights.

See: https://issues.jboss.org/browse/JBDS-4132
Issue: #441 Could not load nodeJSInstall: node-v0.10.22-linux-x86_64
