Feature reward text angle

[Rubinjo]

Added a new feature which lets you put the reward texts horizontally (see image below). I have also made this a prop so you also could go back to vertical. The Example folder and README have also been edited to adhere to the changes.

I have also edited two render sections, so _renderTopToPlay was used again (deleted in an earlier change, I think by mistake) and _textRender was used instead of a duplicate inline code (unused parameters were also deleted from the function).

Example from own project:
