* Strip lookup calls out of inventory variables and clean unsafe data
returned from lookup plugins (CVE-2014-4966)
* Make sure vars don't insert extra parameters into module args and prevent
duplicate params from superseding previous params (CVE-2014-4967)
Commit 7e3dd10 caused a regression with sanitizing the sudo success_key from stdout.
There is no newline in front of SUDO-SUCCESS when using sudo.
This change adapts the regex to make the line break optional.
Tested on Ubuntu 14.04.
At the point the exception is handled, it is likely due to error loading
a sub-template included from main template. Besides file not found, it
can be caused also by include path failing Jinja2 checks. Now, when
rendering the exception from Jinja, it will include exception name. This
will give basic context or *what* the error is.

##### Issue Type:
Bugfix Pull Request
##### Ansible Version:
ansible 1.4.3
##### Environment:
N/A
##### Summary:
We are using a wrapper python script to run ansible-playbook. We use subprocess to execute and print the stdout as and when its written. Problem is when we use pause it doesn't display the prompt string as raw_input does not flush stdout before reading from stdin.
It looks like a dirty fix to add "\n" to the prompt string but i don't see any other way to over come this. If anyone else have a better fix please do propose/suggest.
##### Steps To Reproduce:
```yaml
#File: test_play.yml
- name: Test
hosts: $nodes
gather_facts: false
tasks:
- name: Waiting for User
local_action: pause prompt="Do you want to continue (yes/no)? "
```
```python
#!/usr/bin/env python
#File: test.py
import shlex, subprocess
def run_process(process):
process = process.encode("utf-8")
command = shlex.split(process)
p = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
for line in iter(p.stdout.readline, b''):
print line,
cmd = "/usr/bin/python -u /usr/bin/ansible-playbook -i hosts.txt test_play.yml -e 'nodes=local'"
run_process(cmd)
```
```
shell $ python test.py
```
##### Expected Results:
```
PLAY [Test] *******************************************************************
TASK: [Waiting for User] ******************************************************
[localhost]
Do you want to continue (yes/no)? :
```
##### Actual Results:
```
PLAY [Test] *******************************************************************
TASK: [Waiting for User] ******************************************************
[localhost]
```
