Pin ask staging branch to 0.7.x and update settings

The askbot branches were separated by major versions, in the upstream
repository so this patch pins the ask-staging to the 0.7.x.
The 0.7.x. branch works with django version 1.5.x.

Settings.py now contains the new language configuration options,
including the ASKBOT_LANGUAGE_MODE settings and the required
captcha module.
