Merge branch 'release-1.3.0' into develop
Improved README: grammar and organization.

The README is very complete and useful but had some grammatical errors
and was organized in such a way that the laundry list of options took
precedence over the use examples.  There was also a typo in the example
for exludeFiles which showed using an object when, in fact, it should be
an array.
Merge branch 'feature/update-readme' into develop
Fixed missing code-block closing markup.
Add info re: option inheritance from package.json
Add support for Prefix tag.

This introduces the `prefix` option which generates the RPM Prefix tag
in spec files. This tag makes packages relocatable at install time.

Apply file attributes before post-install scripts.

When file attributes are specified in the options (mode, owner, and
group), these are translated into commands that run in the post-install
section (%post) of the spec file.  This change ensures that these
attribute changes are run before any user-specified post-install scripts
in the case that these scripts require certain permissions or user/group
membership to run correctly.
