Better TableView crate for Cursive

[justnc32]

Since the cursive_table_view crate seems to be abandoned, I made a fork of the project to keep it better maintained and have added some extra functionality to it including another view (ArrayView) as well as the option to enable/disable the sortability of a table, which was always activated in the previous crate whether you wanted it or not.
