Enable composed characters

Fontin does not have all accented characters (e.g, ü or ç). When `compose=yes`
is added to default font features, ConTeXt uses fallback _composed_ characters
for these missing characters.

A discussion on composed characters is out of the scope of this example. Just
think of this as a workaround for an incomplete font.
Disable font features in monotype fonts

This is also a workaround for a wrong default in ConTeXt. By default, TeX
ligatures are enabled for monotype fonts. I think that this does more harm than
good (e.g., \type{--enable} will typeset as "–enable"). So, I disable **all**
font features for monotype fonts.
Enable hanging punctuation

I think that hanging punctuation is useful for presentation. See

for details.
