Adding option for Stop/Reload in location bar for content shell.

Adding option for Stop/Reload in location bar.

Currently reload/stop button is not present in content shell. If user
has to do reload operation then only option to do that is select
the url bar and click go button.Similarly stop button is not present. To stop loading of page only option is to press back button. 
Added code to support stop/reload option.

in java, braces are required unless the statement and conditional can all fit on
the same line.  I think in this case, you should be able to just move this line
up.
