Merge pull request #91 from ManageIQ/install-from-source

Several install-from-source fixes
use dashes instead of underlines in URLs

As suggested by Matt Cutts, from Google; Using dashes instead of
underlines not only looks better; it is better.

For further details, here's a nice writeup:
http://themetaq.com/articles/seo-under-scrutiny-are-hyphens-or-underscores-better-word-separators

At the end of the doc, it brings up additional points (other than search
engine optimization):

1.  Underscores are harder to communicate
2.  Technical words often use underscores in names "FOO_BAR"
3.  Many links are underlined; when there's an underline,
    the underscore is basically invisible.
