[JBERET-84] Remove static instances of repository types from jberet-core
update @since version number to 1.1.0 for certain classes (previously was 1.0.3); add currentRowNum to ExcelItemReaderWriterBase to replace mostRecentRow (in reader classes) and currentRowNum (in writer classes); removed @Ignore for the stress test testIBMStockTradeBeanTypeFullStreaming since it now can pass in 19 seconds.
