Fixes for peers' setFont implementations

[Thomas Fitzsimmons]

Hello,

This patch fixes the implementations of GtkTextFieldPeer,
GtkTextAreaPeer and GtkButtonPeer's setFont methods.  Pango's font
setting mechanisms more closely resemble Java's, which eliminates the
need for XLFD-style font naming.  Also, pango_font_description_set_size
expects the size parameter to be in pango units, not device units.

With this patch, it is possible to change the font family and size for
the TextField, TextArea, and Button components.   Without this patch,
attempting to change the default font on one of these widgets would
cause the text to be displayed at "size 0".

Please review and comment,
Tom
