#34: Make JavaScript display-changing elements (twitter buttons etc.)
display gracefully without JS
 * externalized google analytics code, so it doesn't show in
non-scripting browsers
 * changed the initial links of Twitter buttons, so they include the
desired message content even with JavaScript disabled
 * (won't change the twitter button created within the JS, since if it
is running, then obviously the user has JS enabled... )
 * other minor textual fixes
