typo fixed
SpringAtom - #91

ReportBuilderService updated:
1. saving new SReport instance and two files:
 - compiled jasper report
 - ReportConfiguration (contains all information required to be persisted in order to render report upon request)
 - json based file with report configuration (the letter is a substitute for complex and data model)
2. deleting report and all associated files persisted in file system

rbuilder.beans updated:
1. improved beans in order to make them less self-dependant
2. removed circular dependencies between beans [they need to be persisted as JSON]

xml based cfg
1. pushed several beans into the springatom-application-root.xml to make them accessible for ReportBuilderService as it uses:
 - springAtomConversionService
 - objectMapper
 - change does not affect other beans left in webmvc.xml, they can still access them
SpringAtom - #99

ReportBuilderController:
1. access point to delete method [further call delegated to ReportBuilderService]
2. rendering report by its id and in specified format or in XLS by default
SpringAtom - #86

Update to keep ReportWizard consistent with changes applied in data model of SReport and the way new report is persisted
caching fun...works partially and required further investigation
SpringAtom - #98

changed the link which triggers removing the report - now pointing to the ReportBuilderController
