Implemented automatic rotation for all tile blocks. You can still use
facing properties in model files, if you want to.
Also, some added some fixes and improvements.
Enabled block states ignoring. File with same name as block state, but
with .ignore.json extension. Although it's json extension, it is NOT IN
JSON FORMAT!!! Each line is name of property to ignore. Refers to #10.
Implemented passing of rotations to models. Removed unused unlisted
properties. Included dummy grinder model. Found bugs that have to be
fixed.
Referencing #10.
