Revert "Browser: make sure that only reddit's front page is blocked. All other reddit links are accessible"

This reverts commit 0c0f2af1bd32b9061e391e9d364a21283b14a10f.
The setting is not working. `+reddit.com/*` white-lists reddit front
page
Browser: Block reddit front page but allow other links

I want to force myself to stop accessing reddit from its front page.
Instead I should access reddit from my RSS reader. This way, I break the
habit of refreshing reddit all the time.
