[Feature Request] allow pdf download without remote server

[loudoweb]

Problem :
Base64 method doesn't work for Internet Explorer browser (even last version). If we want the user to download the pdf and we can't use a remote server, an alternative method has to be made.

Solution :
Use a javascript Blob.
Details of the method can be found in FileSaver.js. Additional details on how to create the Blob can be found in jspdf.
This solution can be tested here.
