Update plugin_fastRecordGuide.js

Using direct URL as described in Sonera discussion board <http://www5.sonera.fi/keskustele/viewtopic.php?f=116&t=8286&start=80#p74187> works, but previous/next day links are broken. Updating those links' URL in their click events fixes the problem.

Edit: Thanks for the extension and the effort you've put in, your extension is a life saver, when recording those programs!
