ed278e2279 Removed unnecessary lookup 
The lookup value is the same as the index.  The index in this
case is either a 0 or 1.

James Zern
7bb6a9ccd6 idec: fix internal state corruption 
A call to Append/Update would index the parts_ array w/-1 as num_parts_
had yet to be set by DecodePartition0. This would cause corruption
within the VP8Decoder member.

Fixes issue #106.

89cd1bb85b idec: fix WebPIUpdate failure 
If the first call to WebPIUpdate contained all of partition 0, but not
enough to decode a macroblock the test for max macro block size could
fail (4096 bytes) due to a memory buffer offset not being updated.
This change offsets the buffer in the same manner as Append().

Fixes issue #105.

f07b2138cd Rectify the Chunk parsing logic. 
For odd-sized chunk-payload, there's one Byte padding at the end to make the
next chunk start at even-address. The chunk-skip logic needs to be updated to
handle such cases.
