ERP5CatalogTool class inherits from BaseTool.

Significant addition/changes in:
-------------------------------
  ERP5CatalogTool:
    Add functions _isBootstrapRequired and _bootstrap
    Explicilty add manage option tabs in Catalog Tool

  BusinessTemplate:
    Update BusinessTemplate installation according to changes made in ERP5Catalog and Tool

  testCopySupport:
    Its better to change the tests where they need to call getpath function of
    portal_catalog to use portal_catalog.getpath instead of portal_catalog.getPath,
    as we have overridden the 'getPath' function for CatalogTool class due to change
    in inheritence.

  ERP5Site:
    Create portal_catalog while setting up erp5site
