TODO List
=========

* Placing on ceiling gives "stick attached to ceiling with sign". Shift-click places flat.
* Placing sign flat on fence post makes "stick attached to post".
* Different types of wood? Forestry/Natura/ExtraTrees/BiomesOPlenty
* Full-size signs on block faces (for Slowpoke)

* Ctrl key to counter flat-on-GUI placement.
Q. How do I place a normal sign on top of a <block with GUI>? Sneak-click makes them flat!
A. Hold the CTRL key while you sneak-click: it will negate the sneak-click effect.
