Undo: implement undo of dive site country editing

Simply copy the code of notes editing, but use the taxonomy_* functions
to read and set the value. Moreover, replace the three TAXONOMY_n field
ids by a single TAXONOMY id. We will probably never show one column per
taxonomy field, but rather a single column with a string derived from all
taxonomy fields.
