Access to forrest.properties should use ForrestProperties class

We have added a new ForrestProperties class to the eclipse plugin that allows access to the properties file in a manner independant of how they are defined in config files. However, some of the code access the properties directly. We should remove all direct access and only manipulate/read properties via this class.

Below is a list of classes/methods I know to be affected (there may be others)

org.apache.forrest.eclipse.job.ForrestManager
org.apache.forrest.eclipse.actions.Utilities.activateForrestProperty()
org.apache.forrest.eclipse.wizards.NewViewDocPage
org.apache.forrest.eclipse.wizards.NewXDocPage
