Provide a little more information when dumplog is unavailable.
While testing various permutations, I encountered a couple of
problems with conditionally declared variables.
The Windows data file path has to be constructed because
Windows defines VERSION_IN_DLB_FILENAME.
Keep the personal configuration file details as the last
information displayed.
Have the --showpaths feedback mention whether dlb is in use or not,
and show the container file name(s) when it is. Users of prebuilt
binaries or who build with a hints file instead of picking and
choosing things in config.h might not know, and vms (if it ever
catches up with --showpaths) uses a different container name from
everybody else ("nh-data.dlb" instead of "nhdat").
All Is_*_level tests during early startup would test as true until
dungeon_topology was initialized in a new game or restored from
a save file. That could result in some unexpected code paths being
taken.
The mapglyph() change made a variable obsolete but it got left in
(idx = SYM_PET_OVERRIDE...). Take it out and fix up the formatting
for the block of code that had it.
remove_region() calls newsym() when removing gas clouds, but when
newsym() checked whether it was updating a gas cloud location it
always got a false 'yes' because the region hadn't been removed yet.
Fixing this didn't seem to make any observable difference so it must
be followed fairly rapidly by a full vision recalc.
Don't show the gas cloud glyph at locations where monsters can be
sensed (telepathy, warning, extended detection). It will work
better when/if vision of gas cloud locations gets fixed. (Such
clouds behave as the hero can see into them, so warning doesn't
have any unseen monsters to show unless they're unseen for some
reason other than the gas cloud.)
