Enhancement for ESB mail attachments

Suggestions from: Viacheslav Kabanovich

org.jboss.soa.esb.helpers.Email, and it seems that maybe dialog still should be improved.

Now, the dialog shows jar files and allows to choose jar entries; but code in Email supposes that the attachment path targets a physical file rather than a resource accessible by the class loader.

Will it make sense to remove jar files from the dialog?
-----> I'd say no.

On the other hand, the dialog does not include esbcontent folder, which may contain files, will it make sense to add it to the dialog?
-----> I'd say yes - that would be a good adition.
