Homepage rewrite

Edited opening homepage copy to be warmer, more informative, and more
journalistic. As we add content, we can link keywords in the opener to
various expansions and examples. Removed mention of ABAP, still is
mentioned in your expertise. Reader does not need to know our methods at
first, just our product. But we do need to make sure we can get SEO for
people trying to hire an ABAP consultant. Because we give them a twofer:
ABAP consultant with a bundled front-end.
