Better handling of custom presets in the menu

[InsaneFirebat]

Design a menu to read out custom preset slots and give users a better way to select them. Lines would look something like this, with slot number, area, and current resources displayed.

## AREA HPHP RRR MMM SS PB
or
## Empty Slot

A new action index will handle drawing the preset data and selecting the slot after player input. The macro for preset slots will only need the slot number as text and a constant.
