no bricks are required to show the first look

This semantic change seems to be more straightforward and easier to use.

Changed in this commit:
 * Catrobat-Language version update to 0.9
 * If there's a look in the object it will be shown by default
 * Adapted and refactored test case plus a new one
Merge pull request #635 from Catrobat/usabilityTest
