Retain newline characters in the imported Fix Text and Check Text

[CernerAssociate-ThomasDeranek]

Currently, if multiple newlines occur in a control's check text, only one is retained. As an example, if the following check text is written for a control in a new STIG version:

...Here is some text:

# Here is the example

Here is more text...

The inspec_delta tool will remove the extra white space and the ruby code will resultingly contain the following check text:

...Here is some text:
# Here is the example
Here is more text...

This makes the check text and fix text difficult to read for the more intricate controls. We should enhance this tool to preserve the formatting white space from a STIG or SRG's source material.
