Subject: Changed fonts to freely-available fonts when built locally.

'Arial' and 'Courier New' fonts are not installed in TeX Live by default
therefore when building the spec document using 'makeall.sh' on a Linux machine,
that usually have Tex Live installed, we get fonts error for those fonts.

This patch is checking if those fonts exist on the machine inside the
tex document and if not change them to freely-available fonts:

    Arial -> Liberation Sans
    Courier New -> Liberation Mono
