Text segment doesn't contain the PRG file magic value ($601a), just code.

But I guess it should in general be enough just to use:
	b pc = BasepageTextSegment

Just remember to set it up only after desktop is up, otherwise it will
break once of twice before the Desktop comes up (the basepage of TOS
itself points to somewhere in ROM) and before TOS is fully initialized
the code will complain that basepage is invalid (several "million"
times with TOS4).

Commited with docs update.

PS There's now also new "info cookiejar" command for checking cookiejar
contents as it was only few additional lines.

(Maybe some other things from Atari "sysinfo" program would be nice too.)
