[flexcoders] HSlider - invert / reverse scale.

[Jason The Saj]

I am using an hslider for a project.  My values range from 1-50. 
However, in this case "1" is the higher sensitivity value. 

Currently my slider is as follows:

<-1-------------------------50->

I'd like to change it so that it slides from 50 down to 1. So that the
highest sensitivity value is toward the right (ie):

<-50-------------------------1->

Any suggestions?
