Patch for ASCII Sector 0.7.2 fixing some quests written for an older version.

For details see affected quests' pages and description at start of patch itself. Savegames remain valid.

Only tested with Linux; in theory it should work on Win and Mac, too, if you manage to get a bash script to run. Save the code to a file, mark it as executable and run it in ASCII Sector's top directory. The script makes backups of files it changes, still, no guarantees. Feedback welcome.

 Patches problems in the quests of ASCII Sector 0.7.2.		--JR05/2021

 The quest "The Runners" spawns the escort ship 'Victory' and the pirate
 attackers at the wrong place in Rynkel, because in ASCII Sector 0.7.2 the
 system has more Nav points than when "The Runners" was written.

 The quest "A Lady in Trouble" features a riddle that no longer applies
 correctly, because a new planet, Alasdair Mor, was added early in the list.
 This patch modifies the riddle text to arrive at a solution increased by +1.

 Old savegames remain valid. Only tested on Linux, because that's all I have.
 However we only touch data files, which are identical on Win and Mac, so patch
 should work there just the same if you can somehow manage this bash script to
 run. On Win you'd appearently need to install the "Windows Subsystem for Linux"
 first? Does this include 'stat', 'cp' and 'dd', too? Mac can run bash, I've
 read, but I have no clue where the data files are located, so the script will
 likely not find them. Feedback is welcome.

 On Linux, as far as I can tell, everything is fine. The script does some basic
 checking and backs up the file before changing. Still, use at your own risk.
