In The Dark for Trillian 4

An updated interface for an updated Trillian.

Hah, as if! No, it's only slightly different this time, with a gray background for chat so as to prevent black text from being totally invisible. Trillian 4 gets put In The Dark in this latest port, with exactly the same interface as you've come to expect from In The Dark: A fully grayscale color scheme focusing entirely on black.
