Reviewed it, and pushed to master with some minor modifications.

What I modified are:

1) have the assignment operator return a non-const reference of "this"
object instead of const reference.
2) have the equality and non-equality operators of ScFormulaOptions
return bool instead of int.

Regarding 2), I didn't modify the return type of operator== for
ScTpFormulaItem because it was a virtual function.

Another nice work, Albert.  Much appreciated. :-)
