Block ID update

14w32b all wood types for Fences & Fence Gates
14w33b all wood types for Doors

As Minecraft 1.8 is announced for 2014-09-02 this may be the last block
id update. Until that date I plan to go through all blocks and scan for
missed ones.
Block ID rework

adapted names of some blocks
added missing variants for: monster egg, flower pod and anvil and large
mushrooms
changed default value creation for the "mask" attribute
Merge pull request #44 from EtlamGit/master

final block ID update for upcomming 1.8
fixes to block IDs

large flowers are defined only by bottom part -> made top part
completely transparent
fixed id numbers for new door types
moved alpha definition up

There might be a problem with variant blocks not getting the correct
alpha value if the json file is parsed top to down. Therefore it is
better to define all values to be inheritted by the variants before
defining the variants itself.
fixed depth shading

There was a bug in depth shading with semi transparent blocks on top.
With the new blending Flowers and other alpha<1.0 stuff doesn't pop out
anymore.
Support for viewing/browsing entities on the map
Merge pull request #45 from thewierdnut/int

Support for viewing/browsing entities on the map
Merge remote-tracking branch 'upstream/master'
Fix for entity rendering X error

The pull request from thewierdnut renderes entities at a X position one
towards west. With this change entities are rendered at correct X
position (at least in my tests).
added id for Piston Extension

ID 34 is the head of a Piston and ID 36 is a technical block describing
all the stuff moved by the Piston. But Í have no idea about a good
color.
