JcrRepository need not be final

In my use case I want to expose only one of several workspaces but since JcrRepository is final I'm unable to override getRespositoryInfos() to achieve this. Instead I've inherited JcrService to filter out the RepositoryInfos I want to hide.

It would also help if org.apache.chemistry.opencmis.jcr.JcrRepository#compileRepositoryInfo was protected instead of private so it can be overridden to make small adjustments after calling super.compileRepositoryInfo().
