Today:

	- Row insertion works.

	- Dialog box for adding various things (equivalent to
	  excel's Insert/Cells dialog box, any similarities
	  with Excel are accidental).

	- Plus the usual exciting features you would expect.

	* src/dialog-insert-cells.c: New file.  Handle the insert cells
	dialog box.  This uses GtkCauldron for the first time.  That
	routine is soooo cool!

	* src/sheet.c (sheet_cell_remove): Remove the memory used by the
	key in the hashtable as well.
	(sheet_insert_col): new routine used to insert columns in the
	spreadsheet, it is pretty elaborate.
	(sheet_col_destroy, sheet_row_destroy): New routine used by the
	column-overflow logic in the insertion routines.
	(sheet_cell_add): Only attach a style to a cell if it does not
	have any yet.
	(sheet_move_row): New routine: shifts a row a number of columns.
	(sheet_verify_selection_simple): New routine for warnging about
	the multiple-selections case.  In the future it should provide a
	help context.
	(sheet_insert_row): Implement this new routine.

	* src/clipboard.c (paste_cell): Simplify.

	* src/cell.c (cell_make_value, cell_formula_relocate): New routines
	based on the code that was done for the clipboard.  Now they are
	used in other places as well.  cell_make_value actually fixes a
	potential bug that caused formulas to reappear magically on
	paste-values commands (never hit the bug, but it was there, I
	swear to god).
