Implements SELinux type checking and ensuring.

Whitespace lint fixes

Fixes #66

This renames the `spec/classes/selinux_config_mode.rb` file to the
proper `spec/classes/selinux_config_mode_spec.rb` because otherwise it
never gets run.

These test the behavior when setting `undef` for the `mode` parameter to
the base `selinux` class. The tested behavior is that the module does
not manage the selinux settings at all, leaving the current state the
same.

This is the desired behavior as described in #64, because otherwise
using one of the defined types to manage just a specific selinux rule,
but not manually declaring the `selinux` class and setting the mode
explicitly causes selinux to be disabled. It is confusing (and
undocumented) to use a defined type in a module called `selinux` to set
an selinux rule, and have that result in selinux getting disabled.

configuration to potentially change.

This changes the default behavior for the module to not modify selinux
settings unless explicitly told to. This is the desired behavior as

This changes the default behavior, but it will not change the
configuration of a node in the situation where the node had the class
applied already. However, it will change the behavior in the situation
where the `selinux` class was not included on a node, and then was
switched to being included on the node without any parameters
set (included the situation of a node newly added to Puppet).

This updates the README with a few minor additions that weren't added,
as well as describing the default behavior.

Switch default behavior to not manage selinux

Allow custom package name and management

will fail as you have a duplicate name, this change adds the protocol
name into port definition

Make port exec statement unique for protocol

Pivot to internal types

added hiera support
