Updating to JasperReports 5.5.0

I've updated JasperReports to most recent version, 5.5.0.

jasperreports-functions dependency is available in JasperSoft Maven repository (http://jaspersoft.artifactoryonline.com/jaspersoft/jr-ce-releases). It's required by reports created with Jaspersoft Studio 5.5.0 when one decides to use common functions like DATEFORMAT().

servlet-api dependency is required for report compilation e.g. net.sf.jasperreports.web.util.JiveWebResourceHandler imports ServletOutputStream.
