(MODULES-2410) Add new functions dos2unix and unix2dos

[gibbsoft]

Add dos2unix and unix2dos functions to stdlib so that when using File resources with cross platform templates, the correct line endings can be enforced.

To show usage, here's an extract from README.md:

dos2unix

Returns the Unix version of the given string. Very useful when using a File resource with a cross-platform template.

file{$config_file:
  ensure  => file,
  content => dos2unix(template('my_module/settings.conf.erb')),
}

unix2dos

Returns the DOS version of the given string. Very useful when using a File resource with a cross-platform template.

file{$config_file:
  ensure  => file,
  content => unix2dos(template('my_module/settings.conf.erb')),
}

There are two .rej files wanting to be deleted ;-) Looks very good now, otherwise!

Oops, sorry. Didn't notice them, I guess they were created by the diff. :-o
