[PATCH] paint lines in GtkTree with gtktheme's text color rather than with hardcoded black

[Vlad Harchev <hvv hippo ru>]

 Hi, 

 Here is a patch that will make lines in GtkTree painted with gtktheme's text
color rather than hardcoded black. 
 Please apply it - some apps still use GtkTree (e.g. testgtk, but not limited
to :), and without this patch GtkTrees look stupid.

 Please apply to both 1.2.x and 2.x

 Best regards,
  -Vlad
