Update README.md - add paul-hammant's example

[adabru]

I suggest to add paul-hammant's MySikuliExample to the README.md.

• It is updated to the latest Sikuli version, 2.0.5.
• It is a Maven project that only depends on Sikuli and JUnit.
• It runs on Mac and Windows.
• It is IDE agnostic.
• Duck.ai suggests it when searching for "Sikuli, Maven, JUnit".
  
• It appears at 33rd place when I search GitHub for "Sikuli". Every other example at a higher place depends on a language binding, another framework, or other installed software.
