Added option to pause game instead of disabling autonav when damage is taken
* Comments.
BUGFIX: race2 mission didn't handle the new core systems properly.
On hard mode, the race mission is failed if any outfits are installed.  This included core systems.  It now
requires that only the manufacturer standard core outfits are installed.
Additionally, the AI racers created by addRaw() had two sets of core systems: the base ones and the slightly
better ones added for most craft.  That will need to be fixed as well, but for this mission, I just removed
all systems and installed only the basic core systems.
BUGFIX: Dvaered Goddard had a price of 700,000 instead of 7,000,000
BUGFIX: text boxes were overflowing into each other in the shipyard menu.
BUGFIX: In the info screen, the slots could overlap the quit button and the special abilities could get cut off for some ships, e.g. the Peacemaker
