This adds the microwave tools to GAL in Pcbnew as a new tool:
MICROWAVE_TOOL.
Some new preview items are introduced to support this:
* TWO_POINT_GEOM_MANAGER for managing construction of two-point
geometries, such as that used to construct the inductor.
* CENTRELINE_RECT_ITEM a preview item to draw ractangle with a given
aspect ratio along a line (specified using a TWO_POINT_GEOM_MANAGER)
PCB_TOOL gets a generic event loops which should be useful for more
than just microwave tools:
* doInteractiveItemPlacement() - handles event loops that wait for a
click, create an item on click and then allow moving it
around/flipping, etc.

- 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)
