Falling particles, running particles and breaking particles use the bottom texture of that block

The bug

When breaking blocks, the particles are only from the bottom side texture of that block. This bug it's present since Beta 1.7.2. In Beta 1.7_01 that particles used the texture of the side on which the pointer was.

Also, when running and falling, the blocks use their bottom textures, when it would be more correct if they used their top side texture.

How to reproduce

Sprint on grass blocks or falling on grass blocks, the particles are from the bottom texture.
Hit a workbench on its top side, the particles will use the bottom texture (it's the oak planks texture).
