UIMA AS eclipse launch scripts not setup correctly

The two UIMA AS scripts in the uima-as/examples/run_configuration: UIMA Deploy AS Service.launch and UIMA Run Remote Async AE.launch are setup to only work if Maven eclipse plugin is installed. If the examples project is imported to an eclipse with no maven plugin, the launch scripts fail due to invalid classpath. Remove dependency on maven and setup classpath based on UIMA_HOME eclipse variable.
