* forms: replace re._pattern_type with re.Pattern
Python 3.7 removed re._pattern_type and replaced it with
re.Pattern.
* readme: update for Python 3.7
* Update requirements
Also remove some unused ones which were neither a direct dependency
nor a dependency of our dependencies.
* account: force ASCII usernames on login form
Our database doesn't like it when we check for unicode data in
a column that stores ASCII data, so let's stop it before it
gets that far.
* Move travis CI to Python 3.7
* travis: use xenial dist
* fix newer linter warnings
Apparently bare excepts are literally Hitler, and we have some
new import sorting rules. Hooray!
* requirements: remove six
This is a dependency for sqlalchemy-utils, but we ourselves don't
depend on it directly because we've never been on Python 2 ever.
* Update requirements.txt
Add new tool for developing (lint/autopep8/isort/test)
New tool uses flake8 and isort for lint checks.
Deprecate existing tool (still works)
Update readme
Update Travis config
* Update Travis to Trusty Q2 (they fixed the issue it had before, it works now)
* Fix charset in database creation on Travis to use `utf8mb4_unicode_ci`.
* Make rfc822 filters compatible with Windows systems.
.strftime() is relative to the system it's being run on.
UNIX has '%s' for seconds since the EPOCH, Windows doesn't (ValueError).
Solution: use .timestamp() to achieve the same result on both platforms.
This also allows us to drop the float() around it, since it returns a float.
* Start testing filters
* Add placeholders for more tests
* Make 'tests' folder a Python package
Now you can run tests with just `pytest tests`
* Update readme and travis config
* Test timesince()
* Update and organize .gitignore
Deleted: (nothing)
Added: Coverage files, .idea\
* Test filter_truthy, category_name
* Tests for backend.py
* Tests for bencode.py
* Move (empty) test_models.py to tests package
* Tests for utils.py
* Fixes for flattenDict
* Change name to `flatten_dict`
* `newkey` was assigned but never used
* Add a helper class for testing
* Show coverage on Travis
(only Travis for now...)
* Remove IDE
* Use correct assert functions
* Update README.md
