Remove CATEGORY from addColumn() reference

[jeremydouglass]

Issue description

The addColumn() reference lists the type parameter as taking enumerated argument CATEGORY. This is part of a feature that has not yet been implemented (as mentioned in #497), and so shouldn't be in the public documentation because it confuses users.

type - the type to be used for the new column: INT, LONG, FLOAT, DOUBLE, STRING, or CATEGORY

It's updated in the Table source code. Thank you!

Wonderful, and thank you Casey. Should I close, or does this remain open until the reference is updated in a separate step?

I forgot to close it. I'll do it...
