(trunk gtk) #3887: "CPU spikes to 100% on scrolling" -- workaround committed.

The patch avoids use of GtkCellRendererText's "sensitive" property, and instead renders paused torrents' text using the widget's style's color for insensitive text. This approach honors the theme's "insensitive" color setting and uses it to draw insensitive text with no etching or shadowing.

The better option is still for Murrine to fix its text shadow issue... but until then, here is a workaround.
