Bump django-debug-toolbar from 2.0 to 3.1

[dependabot-preview]

Bumps django-debug-toolbar from 2.0 to 3.1.

Changelog

Sourced from django-debug-toolbar's changelog.

3.1 (2020-09-21)

• Fixed a crash in the history panel when sending an empty JSON POST request.
• Made make example also set up the database and a superuser account.
• Added a Makefile target for regenerating the django-debug-toolbar screenshot.
• Added automatic escaping of panel titles resp. disallowed HTML tags.
• Removed some CSS
• Restructured the SQL stats template.
• Changed command line examples to prefer python -m pip to pip.

3.0 (2020-09-20)

• Added an .editorconfig file specifying indentation rules etc.
• Updated the italian translation.
• Added support for Django 3.1a1. fetch() and jQuery.ajax requests are now detected by the absence of a Accept: text/html header instead of the jQuery-specific X-Requested-With header on Django 3.1 or better.
• Pruned unused CSS and removed hacks for ancient browsers.
• Added the new Panel.scripts <debug_toolbar.panels.Panel.scripts> property. This property should return a list of JavaScript resources to be loaded in the browser when displaying the panel. Right now, this is used by a single panel, the Timer panel. Third party panels can use this property to add scripts rather then embedding them in the content HTML.
• Switched from JSHint to ESLint. Added an ESLint job to the Travis CI matrix.
• Debug toolbar state which is only needed in the JavaScript code now uses localStorage.
• Updated the code to avoid a few deprecation warnings and resource warnings.
• Started loading JavaScript as ES6 modules.
• Added support for cache.touch() when using django-debug-toolbar.
• Eliminated more inline CSS.
• Updated tox.ini and Makefile to use isort>=5.
• Increased RESULTS_CACHE_SIZE to 25 to better support AJAX requests.
• Fixed the close button CSS by explicitly specifying the box-sizing property.
• Simplified the isort configuration by taking advantage of isort's black profile.
• Added HistoryPanel including support for AJAX requests.

Backwards incompatible changes

• Loading panel content no longer executes the scripts elements embedded in the HTML. Third party panels that require JavaScript resources should now use the Panel.scripts <debug_toolbar.panels.Panel.scripts> property.
• Removed support for end of life Django 1.11. The minimum supported Django is now 2.2.

2.2 (2020-01-31)

• Removed support for end of life Django 2.0 and 2.1.
• Added support for Python 3.8.
• Add locals() option for sql panel.
• Added support for Django 3.0.

2.1 (2019-11-12)

• Changed the Travis CI matrix to run style checks first.
• Exposed the djdt.init function too.
