Look for classes in java projects when loading custom views.

Look for classes in java projects when loading custom views.

Even if Java projects can't really contain custom views,
they can contain classes on which the custom views depend.
The ProjectClassLoader now handles these projects.

Changed the way the LayoutReloadMonitor deals with projects
to handle referenced projects.

Also fixed some API returning arrays to make them return lists.
