Pip's name key can now accept remote package address.

Summary:

Pip module would abort when name is a remote package address because
the module was expecting a version if ``=`` is part of the name value.

Furthermore, the pip module would require either name or requirement to
be a key, although the documentation table said neither was required.
The fact that one of them must be present is not documented in the
documentation leads to confusion. This commit added this fact as part
of description.

In this commit, we resolve the confusion by stating either ``name``
or ``requirement`` is needed. Next, if the user puts remote address
as the value of the ``name`` key, we will not use mirror. Lastly,
if the user uses the remote serivice address as the name of the
package and the user does not supply -e option in extra_vars
(which is the whole point of this commit), we will add -e to
 extra_vars so pip command can run with -e option.
LinuxService: avoid enforcing systemd even if init.d script was found
Make package version comparison use globbing.

I have something like:

  apt: pkg={{ item }} state=present
  with_items:
    - python-pysqlite2=2.6.3-*
    - python-paramiko=1.7.7.1-*

But due to the use of *'s in the version specifications, the apt ansible
module always reports changed: true. This patch fixes that.

Add an update option to the git module

This will allow just making sure the repo exists w/out actually making
any chnages to it. Useful if you're going to run a play repeatedly
against a host that might have active development going on in the
repository (think initial bootstrap of a developers system, and
continued playbook runs to work on other projects).
Add support for crypted passwords to password lookup

Added new parameter 'encrypt' with same semantics from that of
vars_prompt. When encryption is requested a random salt will be
generated and stored along the password in the form:
'<password> salt=<salt>'.

Also store passwords with an ending '\n' for easier looking at files
with console tools. File content was being already rstripped so this
is harmless.
