Changes in SUMMARY, DESCRIPTION and whitespace.

Removed the full-stop and repeating package name in SUMMARY.
Removed hard line breaks, broke up some very long paragraphs and
use bullet lists where possible.
All done by browsing through HaikuDepot. There may be (many) more left
in the whole haikuports repo...

Included 10 extended desriptions done by soyoye14 for GCI 2014
(https://www.google-melange.com/gci/task/view/google/gci2014/5240373098053632)

Removed/insert whitespace where it seems to be the custom in recipes.
Sometimes rearranged elements of a recipe (moving license and copyright
up, for example).
