Proposed fix for bug #1222698

Shifted loading of GEDFact_assistant/css/cens_style.css from function formatCensusNote() to the theme header.php as it is required in a number of places. Also took opportunity to change code in function print_note_record() thus removing need for a < br > in the note text to act as a marker for when the header line is to be turned into a link.

Of course a simpler solution to the css loading may be to put the relevant note styling lines into each theme css file
