Bluepower + Carpenters blocks (WIP - Not ready for merge)

-Reworked RedPower2 textures for Bluepower
-Missing: worldgen, some GUIs, all the items
-Added TODO files
-Some GUIs have RedPower2 colors on some buttons
-Added Carpenters blocks frames

P.S: As always, I'm not an artist so fell free to make ANY changes.
Have fun :-)
