website edits

(major priority only so as to get the patch committed before others make site changes...

Hi attached patch makes some grammar edits, adds Christian to the committer page and updates the Talend committer URLs to their blogs, and switches the Ohloh widget from factoids (which presently badmouths the project on every page by claiming few source comments and decreasing development opportunity) to the thin-badge. (The larger partner badge, as well as the stats options which portray Syncope in a better light are other options.)
