Full Parameter Tree: difficult to read parameter descriptions

When the parameter descriptions are very long and don't fit within a single line, MP seems to be center justifying the description. This means that the top and bottom can't be seen. I think it would be better to top-justify.. i.e. make the first line clear, chop off what doesn't fit.


Reproduce the issue in Mission Planner's Full Parameter Tree using a parameter with a very long description and compare the current centered rendering with the screenshot. Trace the parameter-description layout code from that view; done means long descriptions are top-justified so their first line remains visible when the text does not fit.
