New panels ideas and porting existing

I've looked around for cool panel in pyramid/django/flask projects:
1) git history: https://github.com/sjhewitt/django-debug-toolbar-git-panel
2) plot tables relations for sqlalchemy: https://github.com/uralbash/pyramid_debugtoolbar_sadisplay
3) replay ajax calls: https://github.com/jvanasco/pyramid_debugtoolbar_ajax

May be we should add some library like: `aiohttp_debugtoolbar_extras` or own repository for each task.
