Fix documentation issues

minor pdf formatting issue - program listing lines too long:

pg: 9, 14, 19, 20, 30, 31,

Also, pdf formatting seems off for literals included in section headers - the
font is too small.

The publication date is missing on pg 2 (I notice this has gone missing in the
uima-sdk 2.4.2 too)

minor updates for the docbook:

(English grammar) change "allows to xxx" to allows xxx+ing.
e.g.
allows to automatically augment compiled classes: allows automatically
augmenting compiled classes
allows to compose : allows composing
allows to access : allows accessing
