Quick enable/disable speed limit button

[nzgeoff]

Being able to disable any current speed limits with a simple button on the main screen would be very handy!
Functionality is obvious but it would be something like a button on the right of the 'Lock Server' button which when enabled would cause all upload & download speed limits to be ignored so everything would go full speed.

My personal reasons for wanting this are because I run an ftp server from home and only allow full speed at night so it doesn't effect my internet speeds during the day. It would be great to be able to allow full speeds easily at times I'm going out, etc.

Obviously there would be many more uses for a feature like this other than my unimportant example!
