Refactored the elementKey retrieval and made it a separate function. Then added the logic to treat guiclass as an elementkey in addition to nodename.
This is because ConfigElement is not sufficiently specific to display Http Defaults.
reduced the form elements margin for a tighter look
changed font to tahoma
added a new jmxElement class so that any element can now get the dashed border instead of having to constantly add element names to the css rule for dashed border.
Added view for http defaults
Added view for Http Sampler
