Fix for Twitter link in Social Bookmarking Plugin

The plugin uses twitthis.com for posting which appears to be broken. Here's the old code in the Services.ini file of SocialBookmarking:

<site>
<name>Twitter</name>
<url>http://twitthis.com/twit?url={link}</url>
<img>twitter.png</img>
<key>twitter</key>
</site>

Replace it with this to restore functionality:

<site>
<name>Twitter</name>
<url>http://twitter.com/home?status={link}</url>
<img>twitter.png</img>
<key>twitter</key>
</site>

Thanks!
