Merge pull request #1 from RaiMan/master

Updating changes from RaiMan
Changed System printlns to Sikuli Debug instead so there would be
consistent output
Made a change that should allow for the number of VNCScreens in the
static array of VNCScreens to be updated when a new one is created.
With regular screens this would not be a problem because it is not
expected that Screens will be connected/disconnected during the normal
operation of the program, but this can happen with VNCScreens
Merge pull request #50 from mjohnson1/master
