Add removal of sql* commands for apps without migrations to 1.9 release notes

[jillson]

As noted in ​http://stackoverflow.com/questions/34416028/adding-sub-command-sqlall-to-manage-py, it appears that sqlall was removed in 1.9. In addition to the link to the commit in the answer, the documentation no longer describes what the command does in ​https://docs.djangoproject.com/en/1.9/ref/django-admin/ whereas the 1.8 version ( ​https://docs.djangoproject.com/en/1.8/ref/django-admin/) did. The djangon-admin docs (​https://docs.djangoproject.com/en/1.9/ref/django-admin/) does however contain the word sqlall in the example for --color (django-admin sqlall --no-color). Would suggest A) updating the django-admin page to use a different command (unless django-admin somehow still supports sqlall despite manage.py not doing so) and B) updating ​https://docs.djangoproject.com/en/1.9/releases/1.9/#removed-features-1-9 to mention that sqlall (in addition to syncdb) was removed in 1.9.
