Use https links in user-facing startup and error messages

I consider myself lucky that in my circle of friends, `http` urls (as
opposed to `https` urls) are frowned upon in that we generally
apologize in the rase cases that we share an `http` url.

This pull request changes `http` links into their `https` analogues in
the following places:

* In the GHCI startup message (and parts of the User's Guide, where
there are verbatim transcripts of GHCi sessions).
* In a couple of error messages, asking the user to report a bug.

(I also took the liberty to change a single space before the reportabug
url into two spaces, harmonizing this occurence with the others.)

I'm not trying to start a war. I just had a moment to spare and felt
like preparing this diff. Merge or don't merge as you wish!
