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
This is for the out-of-box experience for novice users. It is presumed
that folks with larger more complicated boards will turn it off.

This involved adding some extra infrastructure to be able
to handle the case where a track that is sitting in the
router's commit waiting to be added to the board actually
needs to be deleted instead.

- Finalize transition to BOARD_COMMIT (removed all remaining uses of PICKED_ITEMS_LIST) and implicit view/ratsnest updates
- Simplified SELECTION class, it now can be directly added to a VIEW
- Removed unnecesary casts and templates
- Introduced C++11 features (range based for, lambdas) where they improve code readability
- Added non-undoable COMMITs, which can be used to propagate change notifications to interested listeners (e.g. ratsnest/view)
