No NPE in can_adventure() in Standard for non-item zone

[Veracity0]

Which is a bug I just noticed.

I wrote a test for it and fixed it.

Other things:

• Just as we have ASH can_adventure(location), which is validate1, now we have ASH prepare_for_adventure(location) which is validate2.
• validate2 will now build a dingy dinghy, if necessary, for Island, Pirate, and IsleWar zones
• Modernized a few more switch statements.

The following are (easy) things I am hoping to get in, but the bug is serious enough we shouldn't necessarily wait.
I can easily start yet another PR.

Throne Room:

• King not killed
• Have (and can equip) Harem Girl outfit and either effect or potion of Knob Goblin Perfume
• or have (and can equip) Guardsman outfit and birthday cake.
• (validate2 does all of that; validate1 should pre-check.)
• Tests!

PFA:

• validate2 will use the bean
• Tests!

Isle War:

• have (and can equip) appropriate outfit
• validate2 will equip
• Tests!

Pirate:

• have (and can equip) appropriate outfit
• validate2 will equip

Disguise zones:

• validate1 should check have (and can equip) appropriate outfit
• validate2 will equip
• Tests!

Bat Hole:

• (validate1 already check if have enough sonars for validate2)
• (validate2 uses sonars)
• Tests!

McLarge Huge (and Shrouded Peak):

• Tests!

Investigating a Plaintive Telegram:

• You can only go here if you have taken an LT&T quest
• Having access to an item which will let you select it is good enough for validate1
• (validate2 will detect if you have not selected a quest and will fail.)
• Tests!
