Improved changelog for runserver in 1.7.

  Django takes this information from your settings file. If you have configured

  multiple caches or multiple databases, all cache tables are created.

* The :djadmin:`runserver` command now uses ``inotify`` Linux kernel signals

  for autoreloading if ``pyinotify`` is installed.

* The :djadmin:`runserver` command received several improvements:

* The :djadmin:`runserver` command is now restarted when a translation file is

  changed.

  * On BSD systems, including OS X, the development server will reload

    immediately when a file is changed. Previously, it was polling the

    filesystem for changes every second. That caused a small delay before

    reloads and reduced battery life on laptops.

  * On Linux, the same improvements are available when pyinotify_ is

    installed.

    .. _pyinotify: https://pypi.python.org/pypi/pyinotify

  * Besides, the development server automatically reloads when a translation

    file is updated, ie. after running :djadmin:`compilemessages`.
