There used to be a number of TOOL_ACTIONs that had entries both in
SetTransitions() and the event loop, which seemed redundant and
troublesome.
Now it is not necessary anymore, transitions setup is enough to execute
associated actions.
The footprint editor was displaying the default solder mask clearance
defined by the temporary BOARD object created a start up. Change the
temporary BOARD default solder mask to 0 so the pad or footprint solder
mask clearance setting is displayed when editing the footprint.

The problem with simple deleting VIEW_ITEM_DATA upon VIEW_ITEM removal was
caused by the default copy constructors that copied pointers.
Once a copy of an item was destroyed, the VIEW_ITEM_DATA has been
destroyed, effectively invalidating m_viewPrivData for the other item.
Additionally, fix an unreported bug allowing zoom level to get stuck at
MAX_ZOOM.

Some faults could result in a crash, as they were not properly
handled. Now the rendering loop is wrapped with try..catch block
which will revert to Cairo in case of an error and display an
error message.

This means that non-top-level tools, for example EDIT_TOOL and
PCB_EDITOR_CONTROL can submit their own menus to the top-level tool's
TOOL_MENU, which will then retain a reference to it and make it
available for the CONTEXT_MENU that is shown.
Add a class TOOL_MENU, which provides a management class for a
CONDITIONAL_MENU and a set of CONTEXT_MENUs. The aim of this is to
provide a central place where all TOOL_INTERACTIVEs can get a "basic"
context menu that either they or other tools can register new items and
sub-menus against.
This means that "top-level" tools no longer need to manage the lifetimes
of any CONTEXT_MENUs that they add, and can also delegate simple menu
display functions.
Add a hack so that the pad properties base dialog constructor can pass in the dependency. Since the derived dialog's constructor takes the parent by this exact type, the static cast is safe.
