Minor specs fix (plus lots of whitespace removed)
It's dirty but it works. List scalar and element-wise operations are
both implemented in the improved form. There remains a problem with
casting (what happens if you do :int32 + Fixnum? Is result :int32? or :int64?)

The good news is that slice-by-reference is working for the new
functions in list storage.
Merge branch 'master' of github.com:SciRuby/nmatrix
Allowed non-numeric default values for list matrices.
Cleaned up list scalar and elementwise C functions
Cleaned up list eqeq
Cleaned up list each operators.
Started making additional changes for elementwise and scalar operations.
Incomplete.
