Make Rails 4 Compatible
Use ActionView to render templates of any type

* Removed restriction to erb templates
* Fixed sillyness with overwriting options
remove attr_accessible from GoogleAccounts for rails 4 and modify initializer to allow specifying name of glass application/version for the googleapi client
add optional use of ENV variables to set api keys | use initializer for overriding default behavior
update readme
Pull API keys from ENV not YML
Delete items from glass on destroy

* This keeps you from stranding TimelineItems on the device
Put a parent_id on all TimelineItems
Handle location updates
