Fix mistaken double backslash

The module helper function run_command was appending a literal backslash
followed by 'n' to the stdin of a command it runs unless you called it
with binary_data=True (not the default).  I have changed it to what
I expect was the intent, to append an actual line feed to stdin.
Normalise the module name when comparing against the module names in /proc/modules.
Make sure droplet deletion works even when idempotency is achieved using 'name' and 'unique_name' rather than 'id'
Don't require pycurl in apt_repository when it's not actually needed
Show the offending file name with the include + with_items error
filesystem: Ignore blkid cache

Sometimes, `blkid` will incorrectly return no information about a block
device, even if it exists and has a valid filesystem. This causes the
*filesystem* module to fail if *force=no*. Instructing `blkid` to use
`/dev/null` as a cache file will force it to rescan the block device on
each run, making results more consistent.

Fix issue 5621, rpm_key doesn't work for el5
pause plugin doesn't flush raw_input prompt

##### 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]
```

nova_compute: fix for partial match b/w params['name'] and an existing name

When there is an Openstack instance that has a name that's a partial match
for module.params['name'], but a server with name module.params['name']
doesn't yet exist, this module would fail with a list index out of bounds
error. This fixes that by filtering by exact name and only then getting the
server from the list if the list is still not empty.
