Source citations for NOTE records

[cbettinger]

GEDCOM 5.5.1 specifications states that NOTE records can cite sources:

NOTE_RECORD:=
n @<XREF:NOTE>@ NOTE <SUBMITTER_TEXT> {1:1} p.63
+1 [CONC|CONT] <SUBMITTER_TEXT> {0:M}
+1 REFN <USER_REFERENCE_NUMBER> {0:M} p.63, 64
+2 TYPE <USER_REFERENCE_TYPE> {0:1} p.64
+1 RIN <AUTOMATED_RECORD_ID> {0:1} p.43
+1 <<SOURCE_CITATION>> {0:M} p.39
+1 <<CHANGE_DATE>> {0:1} p.31

In fact GEDKeeper is able to show and resolve references from notes to sources, as you can see in the following screenshot:

It would be great if GEDKeeper could easily add, edit and remove source citations within the create/edit note dialog.

In the screenshot above the full text of each referencing note is shown.

I think it could be a good idea to only show a preview of the text (e.g. the first N characters and ellipses if the text is larger) to prevent "flooding" of the sidebar.
