[feat]: RightClick - Create/Alter all Table types - Promote use of Comments in table CQL with text area comments section

[millerjp]

When you create a table in Cassandra one of the table options is a comments section which is not widely used as I think most people arent aware of its existence.

I want to promote its usage so people use it more my moving it out of the Table Options group and int to the main window. Add a new text area box called Comments below the columns and above the Table Options so people know to enter the text there. Remove it from the Table Options list so its not in two places.

This editable also so it needs to be on create and alter.
