Crash

=================

- Fixed issue where cancelling a ctrl-r search would not return focus.

- Added feature to dynamically load keywords (for syntax highlighting) from
``pg_catalog.pg_get_keywords()``.

=================

- Added the cluster name to the status bar.

- Sort the output of the ``\dt`` (show tables) command alphabetically.

- Improved the color scheme for the SQL syntax hightlighing.

- Dropped support for Python 3.4 and added official support for Python 3.7 and
Python 3.8.

=================

- Fixed an issue that caused a crash when connecting to a CrateDB enterprise
edition with a user that don't have ``DQL`` privileges on ``sys.cluster``.

- Fixed an issue where line comments could only be used at the beginning of a
line and not after a partial statement.

=================

- Fixed a dependecy problem that caused ``crash`` not being able to connect to
CrateDB if an older version of the dependency ``crate`` was already
installed.

=================

- BREAKING: Dropped support for Python 2.7 and 3.3
If you are using crash with Python 2.7 or 3.3 already, you will not be able
to install newer versions of this package.

- Added support for setting the default schema for statements. This is done by
using the ``--schema`` argument on startup.

- Updated the ``\dt`` command to show only tables, but not views. This is to
be forward compatible with CrateDB 3.0 and greater.

=================

- Added support for password authentication.

- Added support for pasting and executing multiple statements at once.

- The `\r` (read) command auto-completion now also shows directories, instead
of only files ending in `.sql`
