* 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
Disables all POSTs, optionally allowing users to log in (without updating last login date)
Blocked POSTs will redirect to the GET endpoint if possible, otherwise to referrer or in last case, home page.
API requests will get a plaintext message with 405 status code.
* Replace all `from nyaa import app` imports with `app = flask.current_app` (or `from flask import current_app as app` where possible)
* Add a separate config object for top-level and class statements as `nyaa.extensions.config`
Required because those codes don't have app context at the time of evaluation/execution.
* Remove `routes.py` file and register all blueprints in `nyaa/__init__.py`
* Refactor `nyaa/__init__.py` into an app factory
* Update tools
* Update tests (temporary, will be replaced)
* Update isort settings
* Apply import sorting (isort) on all files in nyaa/
* Fixed Flake8 errors in nyaa/ (see PR for list)
* Add isort to lint.sh and requirements.txt
