Some cleanup on the 2.0 FAQ carried over from 1.3. May be irrelevant soon,

or it may give us a better starting point for 2.0 improvements.
Fixed a bunch of <p>...</p> matches.
Removed 1.3 upgrade recommendation.
Fixed some entity encodings.
Updated a bunch of links that moved from core.html to mpm_common.html.
Fixed a few bad/stale links.
Fixed a decrement that was interfering with comment.
