Qt status overhaul: add support for 'statuslines'

Condense the Qt status slightly, moving Alignment field from the
Conditons line to the Characteristics line and the Time and Score
fields from their own possibly blank line to the HP,&c,Gold line.

That's for statuslines:2, which is the default.  statuslines:3
restores the previous layout.  I tried to make that become the
default for Qt but it got messy fast and I gave up.

I also tried to make changing 'statuslines' back and forth on the
fly work but failed.  I left the code in as #if DYNAMIC_STATUSLINES
but that isn't defined anywhere.  For the time being at least,
'statuslines' is config file or NETHACKOPTIONS only for Qt, not
changeable via 'O' like for curses and tty.

Change the option description for 'statuslines'.  That depended
upon whether curses was compiled in when it should depend on which
interface is active.  This moves the alternate info to Guidebook.

+A value of {\tt 3} renders status in the {\tt Qt} interface's
