Also fixes a bug where Convert Symbol wasn't undoable.
Also cleans up some SetModified() call no longer needed with SCH_COMMIT.

RTree.

While a SCH_SHEET does indeed have a SCH_SHEET parent, it's not one of
the children that gets added as a CHT_MODIFY of its parent.
Also fixes a bug where the newly drawn sheet gets removed from the
preview before running the dialog.

The connection graph should only be updated within the commit structure
because this is the only time the connectivity should be changed. We
want any connectivity changes to be included in the commit as well, so
this should be stored prior to the undo/redo list mods
Note that this only works where a BOARD_COMMIT or SCHEMATIC_COMMIT is used.
(BOARD_COMMIT is used almost universally in PCBNew, but SCHEMATIC_COMMIT
has very little adoption in EEschema so far.)
Provides a single-point access for modifying the schematic and symbol
elements that allows chaining updates and reverting partial changes.
Standardizes the undo hierarchy between pcb and schematic editors
As this is another layer on the existing undo/redo structure, the
initial commit does not replace all undo/redo calls currently existing.
These will be handled in a series of follow-on commits
