[request] notification that sikuli is running

Hi,

I have fixed this, please find the fix in the attachment.

my solution is as follows

1. SikuliTrayIcon is the class responsible for using system tray add and remove functionality.

2. Show/Remove functions of SikuliTrayIcon class are made from ScriptRunner.java runPython() function.

I am sorry for not providing diff but let me know if it acceptable.

my sikuli code version is : SikuliX_DrvBR_Rev930

@ Vikram
Thanks for your contribution.

First impression:
- messages should be according to Sikuli's message concept
- where should the icon image be stored in the different distributions? Shouldn't it only be available in the Windows distribution?
- The loading of the icon image should have an exception handling.
- the TrayIcon feature should be in Win32Util and used with the support of OSUtil.
- showSikuliTrayIcon is called in all cases, but removeSikuliTrayIcon only if the script execution succeeds (does not produce any exceptions). This is at least risky.
- in the show processing the tray support is checked, but not in the remove processing!

The feature as such seems to be rather simple to use (content of class SikuliTrayIcon), but the integration into the script running workflow and the build process with respect to the fact, that Sikuli supports Windows, Mac and Linux, has to be optimized.

@Vikram, please make a pull request on github. This way should be easier for both of us.
