- Updated to TAG "0.1-4"
- Added a new function to rotate textures (as :SetRotate() sucks as it seems to
  resize them as well!). The new function is called "SetRotation" and is practally
  a copy from: "http://www.wowpedia.org/SetTexCoord_Transformations#
  Simple_rotation_of_ square_textures_around_the_center". to use it:
  "SetRotation(texture, angle)". texture is just a pointer to the texture you want
  to rotate and angle is the angle you want it to end up at (positive is Counter
  Clock Wise). For example angle = 90 would move it to 9 o'clock and angle = 270
  would be 3 o'clock... If you keep giving it the same angle (say 90) it won't
  move it another 90deg it will just move it to 9 o'clock again and again.
