[JBossTools Runtimes] Allow user to select what runtime types to be added

If user searches for a runtime(s) he adds folder wich contains typically EAP or SOA. But EAP or SOA contains several runtimes, which are added if user decides to add the runtime as whole. Runtimes that will be added are printed in description section.

User shlould have the right to decide what runtimes will be added. I suggest to display found runtime as tree with checkboxes.

For example SOA runtime should look like:

• /opt/soa-5.0

  Server runtime 5.0

  Drools 5.1

  Seam 2.2
