Develop JUnit for node.js tern server

Develop JUnit for node.js tern server.

@pascalleclercq : initialize maven to do JUnit and JUnit must work with any OS (start the well node exe).

@pascalleclercq I have added a simple JUNit with Tern server and node.js at https://github.com/angelozerr/tern.java/blob/master/core/tern.core.tests/src/tern/core/tests/NodejsTernServerTest.java

As you can see I have hard coded the path of the node.exe for win32. The path should be dynamic (computed according the OS).

Mostly done, see https://opensagres.ci.cloudbees.com/job/tern.java/

3 tests are in errors though:

• tern.server.nodejs.process.NodejsProcessTest.badNodejsBaseDir
• tern.server.nodejs.process.NodejsProcessTest.ok
• tern.server.nodejs.process.NodejsProcessTest.badNodejsTernBaseDir

alternatively we can use this (easy) trick on cloudbees and assume node is always in $PATH of the build.

This would avoid tricky maintenance on node versions.

Good job Pascal! I have fixed problem with the 3 JUnits an build works now. I close this issue.
