Removed apptentive ratings, added some tool tips, and some fixes.

[REMOVED]   Stop using apptentive for rating questions.  Pearl's
            built-in functionality seems nicer and more basic.
[ADDED]     Some more tool-tips to help the user, to be shown on first
            run only.
[FIXED]     The site name tip wasn't showing anymore.
[FIXED]     Some language and formatting in help.html.
