Highlight currently executed instruction in internal editor

[trdthg]

close #124

• New
  • add Machine::addr_to_blocknum
  • add SampleAsm::address_to_blocknum

when core_step, machine send signal to editor

• highlight block
• scroll to block's first line (show in editor middle)

It looks very good. Good job. But it should be optional. I would like checkboxes in the Options pane to: enable highlighting, and enable focus change. Also a button to trigger the highlight manually would be nice.
One slight nit pick: I would prefer the highlight to cover the whole line (to the right edge of the window), not just the text. To stay consistent with error highlighting.

• two options added
• highlight now cover the block and an extra \n

Also a button to trigger the highlight manually would be nice.

you mean add a button (for enabling highlighting) at the same time?

It looks very good. I have just changed some texts. But I have noticed one problem - this does not make that much sense in pipelined settings. Could you hook it up to the focus selection in program view?

fixed, when machine reload, the connect between machine and editor lost

[machine]X -> editor

now rebuild connect between new machine and mainwindow when machine reload:

machine -> mainwindow -> editor
