Make signs writable

Solutions:

• Using the text rendering of minecraft
• Using custom fonts (licensing though?)

Duplicating the drawText() method of GlobalRender.java would allow to render text in MC font.

This works (but only client-side):
Minecraft.getMinecraft().ingameGUI.setOverlayMessage(playerMessage.internal, false);

It's okay for now.
