Docs: Improve example in merge function

This commit replaces the example in the merge function with a much clearer
one. It also mentions that the rightmost value wins in the event of duplicated
hash keys.
Docs: Update file_line documentation

This commit clarifies the behavior of the file_line resource type.
Docs: Update documentation of stdlib classes

This commit edits the puppetdoc text of the stdlib and stdlib::stages classes
to remove redundancy and add additional information.
Docs: Correct indentation of markdown code examples

Code examples in several function doc strings were only indented by two
spaces, which would not result in proper display when rendered as HTML. This
commit corrects the indentation to four spaces.
Docs: Copyedit function doc strings

This commit makes several minor consistency and wording edits to the doc
strings of the stdlib functions.
Docs: Remove author emails from stdlib functions

Author email addresses were included in the doc strings for some (but not all)
stdlib functions. This commit removes them in the interest of consistency.
Docs: Clarify the use case for the anchor type

This commit tweaks the docs for the anchor resource type to give more context
for its existence.

(#10802) add new function get_module_path

This commit adds a new function called get_module_path.

get_module_path returns the absolute path of a specified module. The
code and functionality is very similar to how templates and files
are detected inside of modules.

the function has been tested against puppet 2.6.10 and 2.7.x

(maint) Add semantic versioning info to README

it relates to Puppet Enterprise released versions.

(#11607) Add Rakefile to enable spec testing

Without this patch the 2.1.x branch does not have a Rakefile like the
2.2.x and master branches do.  This is a problem for the continuous
integration testing since it executes `rake test` against 2.1.x, 2.2.x
and master currently.

This patch fixes the problem by copying the Rakefile into place enabling
the `rake test` task.
