Compat patch

My object was to fix the appearance of the example in pre API14 devices by not referencing the color from the platform color, but from an inner colors file, in which I inserted the color copied from the apI level 14 res > colorr.xml file. So the programs looks exactly the same, but well on every devices!

* Added colors.xml file with the refered colors (Blue, green, red, orange)
* Changed minimum SDK version to 8 and Target SDK to API 18
* Changed the the COLORS array to reference the color from colors.xml file and not the andori SDK color file

PS: the changes in the .settings folde, discar if necessary...I tested the program in my phone (Android 2.3) and in my friends phone Android 4.2, and in an emulator (Android 4.03) both worked well, Cheers
