Debugger improvements

[holub]

We have very powerful debugger but it's mostly created for M.A.M.E. developers and very alien for developers who want to use it for development in target platform.

Some things which can be considered for improvements:

1. Run and start without breaking into debugger
2. Historical values for registers
3. Grouping view (e.g. for ports D-values)
4. Custom view for data region with defined names for offsets. Can be useful in REGs arrays.
5. Configurable key mappings

1. Run and start without breaking into debugger

This can be gotten around by using -debugscript and making a debug.txt file with "g" as the only line.
Then launch MAME with added: -debugscript debug.txt

That is awesome! Not too user-friendly though

There are no custom hotkeys in dubugger or am I missing?

5. Configurable mappings:
   Custom window in debugger which allows to set up table with name and lua value.
   I think that covers (4)

All of these seem like great ideas, I eagerly await you implementing them.
