Improved project page description for Talk module

The talk project page is a little terse. Here's some proposed text:

The talk module removes comments from the node page and puts them on a separate tab. This style of commenting is very popular on Wiki sites (usually called the "discussion" page) and on news websites where the goal is to separate user generated content from editorial content.

When installed this module will add a tab to the set of tabs at the top of a node view page like "View | Edit | Talk".
