0.3.5b1

Added special handling for automation entities. These are now handled slightly differently from other entities. The differences are as follows:

• The last_triggered attribute is used for the timestamp rather than the last_changed attribute, allowing them to be sorted by when they were triggered
• Automations which have never been triggered (last_triggered is None) will be excluded
• The state of automations will always be "Triggered", so will display by default as "Automation Name @ Triggered" in the feed (this can be overridden as normal using the content_template option)
