Improvements to ASM window. 
 - Can now display ASM independantly of IL/C# lines.
 - Displays all ASM for current method.
Fixes:
 - VS error message when closing VS during a debugging session
 - VS can now do multiple debugging session in a row without needing restart. Issues: 
        - Unhandled exceptions in DataReceived event handler caused UpPipe to break resulting in total loss of connection between AD7Process and ToolsWindows
        - Added new code to clean out the Action handler that PipeServer uses. By holding onto the old Action reference, it was holding onto a reference to the old AD7Process instance thus reulting in all sorts of weird errors.
ASM window now scrolls to approximately the correct place for current line.
