Memory rendering

• Ted will try to contribute the traditional rendering to platform.
  • There are possible issues with the rendering being extendible.
  • If the contribution is not acceptable for platform we can contribute it to CDT.

Disassembly

• If instruction stepping mode is on, disassembly should be shown by default.
• If disassembly view is opened, instruction stepping mode should turn on by default.
• If the disassembly is opened because file didn't have source for a function, when debugger steps out of that function the editor should be shown again.
