Windows CE changes (from <Someone>)

The changes did not apply to the main trunk as easily as I wouuld have
hoped, so I attempted a number of manual applications. I hope <Someone>
can tell me if there is a problem.

Changelist:
- bugfix: help text windows close immediately after open (unhandled WM_KEYDOWN in mhtext.c)
- bugfix: action button uses hero coordinates instead of cursor position
- pocketpc: bugfix: menu window closes on up/down keys from first/last position
- smartphone: do not translate input when command helper is hidden (fixes Motorola Q keyboard bug)
- smartphone: new keypad layouts
- smartphone: wizard mode command layout
- smartphone: option to feed arbitrary text as a command to nethack core
- wrap/unwrap text option for text windows
- hardware keyboard detection
- hide keypad when hardware keyboard is present
- backport message window highlighting from winnt port
- new icon with recommended image sizes
