Removed blueprint-handlers.xml

Removed blueprint-handlers.xml from cae-base-lib without replacement. The file provided the abstract beans pageHandlerBase, defaultPageHandler, and defaultPageActionHandler. The dependencies assigned to these abstract beans have to be assigned explicitly in handler beans as Spring java config does not support abstract beans.

Change Link Building/Handling for Transformed Blobs

Methods buildLink and handleRequest of com.coremedia.blueprint.cae.handlers.TransformedBlobHandler have been changed to generate / validate the digest url segment based on the ETag of the actual transformed blob which respects the width/height parameters and the effective Responsive Image Settings.

This means that new links are generated not only when the local transformation string of a blob changes but also when the effective Responsive Image Settings change.
