Describe our IP regime in the "Starting a new Eclipse Open Source Project" section

Some of this may already be there:

• Projects must engage in the Eclipse IP Due Diligence Process
• Committers must sign a committer agreement
• Contributors must sign the Eclipse Contributor Agreement or be covered by a committer agreement
• The project team must not add additional burdens (e.g., no CLAs).

While we're at it, we should reinforce that:

• After the project is created, up-and-running, new committers are added via committer election after making a demonstration of merit (yes, we really mean it).
