Modifications to the figure image (figures/kernel-title.png),
the heading styles (style.css), and the numbering system with
TOC display (yocto-project-kernel-manual-customization.xsl).

I updated the title image to display the manual title using
color #00557D, which coordinates with the Yocto Project website
color scheme.  I also updated the style sheet to use this same
color for the section headings.  This helps to set them off better
from the text.  Finally, I flipped the switch back on for this
manual to create chapter-specific table of contents sections
prior to each chapter and to include a all-inclusive TOC at the
beginning of the book.

Updated the figure to not use "preempt_rt".  Now uses "preempt-rt".

This is the first draft of the Yocto Project Kernel manual.  The
manual consists of two sections: concepts and a practical section that
has examples.  It is based of Bruce Ashfield's kernel theory paper.
This first draft has been re-written and organized through the
concepts section.  The remainder was just placed in as-is due to
time constraints for getting some kernel documentation up on the website.
The manual still needs scrubbing and organization in the latter half.
