resolves #135 allow theme to control layout of title page

- theme: use absolute top position for document title
- theme: margin top & bottom for all text elements on title page
- theme: text alignment on title page
- theme: revision info delimiter
- rename title-logo attribute to title-logo-image
- absolute top position for image logo (theme or from document attribute)
- parse title-logo-image attribute value as image macro (if used)
- title logo image size and alignment
- update example to include subtitle and logo image scaling
- fix theme_font so all properties are inherited (except heading size)
- minor code cleanups
