Put in a very basic help browser on '+'. This is *not* a good key, I'm just

parking it here until more decisions on the browser come in. (It should probably
be reachable by pressing '?' from the current '?' help screen.)
It reads the manual from ../docs/crawl_manual.txt, so you'd better put it there!
Yes, this is a hack and will have to be done better.
You can press the letter of the section (e.g., 'j' or 'J') to jump to that
section.
