Etlhelper

This is a minor release to allow schema-qualified table names e.g. `schema.table` in the `validate_identifiers()` and to apply the validation to table names passed to the `copy_table_rows()` function.

What's Changed
* Allow schema-qualified names in validate_identifier by volcan01010 in https://github.com/BritishGeologicalSurvey/etlhelper/pull/141
* Validate table name in copy_table_rows by volcan01010 in https://github.com/BritishGeologicalSurvey/etlhelper/pull/142

This release is a minor fix to allow the test suite to pass in Python 3.6.

What's Changed
* Py36 fix by volcan01010 in https://github.com/BritishGeologicalSurvey/etlhelper/pull/138

This release adds the following new features:

+ The `generate_insert_sql` function (used by `load`) validates the table and column names used. As these are user-provided they were a potential route for SQL injection attacks. An `ETLHelperBadIdentifierError` is raised on bad input.
+ The `abort_etlhelper_threads()` function has been added. When called, this raises an `ETLHelperAbort` exception at the end of the current chunk. It can be used to cancel jobs that are running in threads, such as in GUI applications. See [README.md](https://github.com/BritishGeologicalSurvey/etlhelper#aborting-running-jobs).
+ `list_row_factory` and `tuple_row_factory` have been added. Data can now be exported as all of the main Python container types e.g. namedtuple, dictionary, list and tuple. Lists are mutable so are convenient to use with transform functions. Tuples are fast to create and access. See [README.md](https://github.com/BritishGeologicalSurvey/etlhelper#row-factories)
