Adding play for continuous integration, ora bug fix

* ora user wasn't created during initial configuration run
* removing forked ec2 module
* updating ec2.py and ec2.ini to latest ansible repo version

+# When generating inventory, Ansible needs to know how to address a server.
+# Each EC2 instance has a lot of variables associated with it. Here is the list:
+#   http://docs.pythonboto.org/en/latest/ref/ec2.html#module-boto.ec2.instance
+# Below are 2 variables that are used as the address of a server:
+#   - destination_variable
+#   - vpc_destination_variable
+
+# This is the normal destination variable to use. If you are running Ansible
+# from outside EC2, then 'public_dns_name' makes the most sense. If you are
+# running Ansible from within EC2, then perhaps you want to use the internal
+# address, and should set this to 'private_dns_name'.
+destination_variable = public_dns_name
+
+# For server inside a VPC, using DNS names may not make sense. When an instance
+# has 'subnet_id' set, this variable is used. If the subnet is public, setting
+# this to 'ip_address' will return the public IP address. For instances in a
+# private subnet, this should be set to 'private_ip_address', and Ansible must
+# be run from with EC2.
+vpc_destination_variable = ip_address
+
+# To tag instances on EC2 with the resource records that point to them from
+# Route53, uncomment and set 'route53' to True.
+route53 = False
+
+# Additionally, you can specify the list of zones to exclude looking up in
+# 'route53_excluded_zones' as a comma-seperated list.
+# route53_excluded_zones = samplezone1.com, samplezone2.com
+
+# API calls to EC2 are slow. For this reason, we cache the results of an API
+# call. Set this to the path you want cache files to be written to. Two files
+# will be written to this directory:
+#   - ansible-ec2.cache
+#   - ansible-ec2.index
+cache_path = /tmp
+
+# The number of seconds a cache file is considered valid. After this many
+# seconds, a new API call will be made, and the cache file will be updated.
+cache_max_age = 300
