Issues with unsupported toolkit functionality

[fra.orolo at mailfish.de]

Hi,

I'm currently porting our FEST test suite from using Xvnc to Cacio.
In general it seems to work quite well but there are a couple of
API-Methods of CTCToolkit which are not (really)
 implemented yet, although I think it should be quite simple to do so:

* currently the getScreenResolution() method returns 0, (which is
pretty much the worst number in this position)
  a constant 72 or 96 would help a lot.
  A possibility for dynamic configuration in tests would be great.
  We have a lot of Screenshot/Save Image actions which use this number
for a division and currently crash.

* getSystemClipboard() currently returns null. Although I understand
that a fully-fledged implementation would require
  some intelligence but I believe in tests it would be sufficient to
create a singleton instance of Clipboard in the toolkit, that can
  be filled and read by java test and client code.

* We are supporting only Oracle JDK. This works in general quite well
with Cacio, but there is an Issue in the following method:

These are my observations so far, anyway: Great Work, will save us a
lot of trouble in the future.
