jberet-support: upgrade jberet-parent, jberet-core, jberet-se to 1.4.5.Final, and fix resulting Excel reader/writer errors

upgrade jberet-parent, jberet-core, jberet-se from current 1.4.0.Alpha to 1.4.5.Final.

remove the repo (http://jasperreports.sourceforge.net/maven2) , since the jasperreports artifacts have been made available in central.

As a result of the above upgrade, ExcelReader and ExcelWriterTest failed, due to:

• poi 4.1.2 (upgrade brought in by jberet-parent upgrade) introduced new type CellType, and MissingCellPolicy
• poi 4.1.2 requires xmlbeans version 3.1.0

Some errors from the above ExcelReader ExcelWriterTest:

java.lang.NoClassDefFoundError: Could not initialize class org.apache.poi.ooxml.POIXMLTypeLoader
