pages: Indentation fixup for admin button.
pages: Add destination parameter to adminon/off.
VDestination: Fix bug where https URLs weren't validated.
login.js: Redirect appropriately from login popup.

The login popup redirects to a link's href if one is present. This works for
all links, except for the login link which is hrefed to /login for middle
clickability. This ignores the login href specifically which results in the
current page being reloaded correctly.
redditheader.html: Reload current page on logout.
reddit_base: Optimize parsing of request_origin.
sidebar-message: Tweak <p> spacing.

This fixes the small amount of extra space at the bottom of a sidebar
message that contains only a single <p><strong>...</strong></p>.
Subreddit names should only have ASCII characters.
ratelimit: Stop advertising #reddit-ratelimit.

Since it's low traffic, I mostly don't notice until the user has already left.
Also, IRC illiterate users tend to expect a response in a few seconds.
