Added some new tutorial events (not tested with the tile build):

* Auto-explore hint (200 turns after level map hint).

* Explanation of the "Your equipment suddenly weighs less" message.

* Explanations of trap and heap branding (non-tile builds only).

* A note that monsters that have moved out of LOS haven't just vanished.

* Events for gaining an ability from a mutation and gaining one from
  an item which was just equipped, separate from the event for the first
  divinely granted ability.

* An explanation that shouting monsters have just noticed you, plus that
  their shout is likely to attract the attention of other monsters.

* A "seen portal vault entrance" event, since the entry to the sewers can
  appear on DL 3 through 6, and there's also a very small chance of a
  Zigguart entrance apearing as early as DL 3.
