Updated math to use Math.round to help get better values. Updated code

for determining if Vera is available so as to not show those screens.
Updated file handling as there were issues due to no checks for file
handling, this will improve for windows.

 The argument for the vera address should be given as it the system does not have a way to find the address. Supply -Dvera.address=X.Y.Z.A on the command line to provide it. If a vera is not used, do not set it.

 ## Dimming and value passing control
-Dimming is also supported by using the expressions ${intensity.percent} for 0-100 or ${intensity.byte} for 0-255 or $intensity{match(<your expression using "X" as the value to operate on>)} i.e. "$intensity.math(X/4)}".
