Some more reformatting according to uncrustify results.

Moved VIEW_GROUP creation to the selection tool. In this way selected items are always drawn on overlay, not only when dragged.

Added Init() to TOOL_INTERACTIVE, allowing to set up things that are needed to be initialized only once.
TOOL_ACTIONs can be run from CONTEXT_MENU after adding them.
Move tool actions are available to be run from CONTEXT_MENU displayed after right mouse button click on selected items.
Added some asserts to check the code.

Added rotate & flip to the pcbnew.InteractiveMove tool, hotkeys for them and undoing all the  operations on cancelling the tool.

Removed TA_ActivateTool (now tools are invoked by sending TA_Action event, with the tool name as string parameter).
Developed TOOL_Action class & added ActionManager. Hot keys registered by tools are processed.
Selection & move tool can be invoked by a hot key.

Removed selection disambiguation in case when there is a choice between a footprint and a smaller component (smaller components have priority).

Smarter selection algorithm (does not allow to select both whole MODULE and its parts at the same time).
Cancel event works better (selection box does not appear after cancelling the selection tool).
Removed blinking selection box effect.
Model is accessed in more appropriate way (getModel() method).
