Fixed paragraph title.
fixed several typos, bad sentances and actually rewrote the figure/image titles because they were all just <<installing truecrypt>> which is not very descriptive / helpful.
images were too large in the final compiled PDF, reducing size to prevent them going off page.
resized all of the oversized images using mogrify -resize '450x>'
improved the build system and added new script for conversion to .epub
added two lines on how to compile the handbook
added some imporant lines to .gitignore to avoid adding the new build objects
finally got gitignore correct to remove all build artifacts except the book.md in src/ folder
