[bitbake-devel] [PATCH 3/8] toaster: add commands to list and delete builds

[Alex DAMIAN]

From: Alexandru DAMIAN <alexandru.damian at intel.com>

We add Django commands for the manage.py to manage the database
content.

The two commands added are:
* buildslist - produces a list of current builds
* builddelete - deletes a build and all associated data from the database
