fixed the bug 396528
- Increased the size of curveWidget and now it's taking all space available by own its own.
- also in some of the sensors there is some explanation provided along with values in Qlabel.so,made the label to appear in the the Tool-tip for better view and also underlined the labels who have tool-tip for everyone to know that there must be something out there like tool-tip.( as discussed on irc with scottyp as this will going to help him on his patch).
- Updated some minor changes in the dialog like size of push buttons etc.
