Rename "datasize" to "size" in dimdata structures.
Rename 'gridsize' to 'proc_grid_size'.
Rename 'gridrank' to 'proc_grid_rank'.
Rename 'disttype' -> 'dist_type'.
Rename 'blocksize' -> 'block_size'.
Rename 'dimdata' -> 'dim_data'.
Remove 'bc' and 'bp' dist_types.

Block-padded *will* be replaced with optional padding keys on 'b' and 'n' distribution types.
Don't `--use-mirrors` in .travis.yaml.

Change the id code for no-distribution to 'n'.

It was the object None, which allowed for using Python's implicit treatment of this value as False, so this change is a little more subtle than the others.
