#196 Blob - Add proper mean to enter data in a blob, without ambiguity.

[Hans Deragon]

Add proper mean to enter data in a blob, without ambiguity. For instance in an XML or CSV file used as input, the following entries can be provided to enter data in a blob, without any confusion.

        [text]This is text with UTF-8 (the default) characters >>àéç<<
        [text UTF-8]This is text with UTF-8 (the default) characters >>àéç<<
        [text]c27ccbf5-6ca1-4bdd-8cb0-bacfea6a5a8b
        [base64]VGhpcyBpcyBhIHRlc3QgZm9yIGJhc2U2NC4K==
        [file]/home/<user>/testfile.txt"

The best new feature is [text <encoding>]</encoding>, allowing to enter text in the desired encoding scheme. We used it for encoding in ISO-8859-1.

The code has already been written, including the tests with it. I want to create a pull request so you can check the code, but I do want you to reject it so then I can work on some documentation, for a final pull request.
