Updates to the unit tests of the lib.text.table.format_table() function.

Fix for the lib.text.table.format_table() function - the column width calculation was broken.

Fix for the unit tests of the lib.text.table.format_table() function.

The function currently expects all table contents to be strings.

Fix for the lib.text package __all__ list - the module is 'table', not 'tables'.

Created two unit tests for the lib.text.table.format_table() function.

Created the framework for the unit tests of the lib.text package.

Added the spacing argument to lib.text.table.format_table().

This removes the reference to the user function table spacing variable from this function and shifts
it to the prompt.uf_docstring.create_table() function.

Fix for lib.text.table.format_table() as table_line() is now private.

Deleted prompt.uf_docstring.table_line() as this is now a private function of lib.text.table.

Removed a number of unused imports in prompt.uf_docstring.
