PANICTRACE (stacktrace on panic or signal) + bits

On crash signal or panic(), use a configurable method to get a stacktrace
the user can easily report to us.  Currently only for Unix/Linux and only
ifdef BETA.  Hopefully ports can add additional methods.

Bits:
- linux hints file had PREFIX definition in the wrong place
- sample sysconf file used wrong delimiter for WIZARDS
- fix grammar error in support message when using sysconf.wizards
- options.c comment typo
- capitalize "Crash test" output from #panic command
