ENH: add the new template files to ReferenceAtlas/20141004_BCD directory

The current LLS model file (LLSModel_50Lmks.h5) and template model
file (T1_50Lmks.mdl) are updated.
New model files have version ID (version=2.0) embeded in them.
ENH: Remove wrong model files and update AutoWorkup scripts

The wrong model files directory (ReferenceAtlas/20140916_BCD) is
removed, since all corrected model files are placed in a new directory
called "ReferenceAtlas/20141004_BCD".
Also, AutoWorkup script is updated to have the new address of the model
files.
ENH: Update the BCD model files for internal TestSuite
