Debug Window; Useability enhancements

The Debug Window has had the following useability enhancements:

• A new "Hide common SQL" checkbox has been added (checked by default)
• This currently only hides the following active User query which is run frequently (where [Pk] = 1 may vary):
• SELECT [Active] FROM [User] WHERE [Pk] = 1 AND [Deleted]=0
• If the User is focused in the details textbox below the grid, any incoming traces no longer cause the grid to jump to the last row
• If the User selects a grid row, when the grid automatically updates, it will no longer jump to the last row
• The User can now press Escape when focused on the grid to deselect the current row which will cause the grid to resume jumping to the last row whenever a new trace notification arrives
