#4 Use javax.swing.text.Style for Highlight

[Gillmer J. Derge]

The highlight is displayed using the
javax.swing.text.Highlighter mechanism. This means
that the highlight can only change the background but
not the text's foreground or the font. Using
javax.swing.text.Style would allow more elaborate
control over the look of the highlight.

Note that due to the way styles are implemented in
JBuilder this may be quite difficult or impossible.
