Akonadi: preliminary support for KJot

Added preliminary Support for KJots's custom format of storing Akonadi Notes.
Currently it is assumed that all the notes it stores is of Plain Text format
(as happens in the AkoNotes Plasmoid).

Later on will have to dig into implementing support for notes in HTML and other
formats too?
