Create Custom Plugin Interface/Abstract Class for Custom Builder

1. Create a maven project contains only plugin interface, abstract class and APIs. This maven project will share with other developers who want to extend the feature of a custom builder.
2. Include the maven project as a dependency of the custom builder project.

3. Modify the custom builder project POM file to adding the package of plugin interface, abstract class and APIs to the <Export-Package>.

   <Export-Package>org.joget.pbuilder,org.joget.pbuilder.api.*</Export-Package>

4. Register the plugin interface and abstract class in Activator class

   PluginManager.registerCustomPluginInterface(new CustomPluginInterface(PageWidget.class, "pageBuilder.pageWidget", PageBuilder.MESSAGE_PATH));
