Proportions Version 2.0 available

[Gorgo]

This is what Mephisto posted at the time:

Version 1.64:
1. Fixed - Resource modifiers were going into negative percents.
2. Fixed - Integer overflow with large numbers of units in combat.
3. Changed - Increased the "maximum number of ships per player" and the
"maximum number of units per player" selection to have an
upper limit of 20,000 each on the Game Setup screen.
4. Fixed - Maintenance cost displayed for designs was not taking into
account abilities of that design.
5. Added - You can now use an AI_Construction_Units.txt file with your
AI. The file will only be used if it exists. This supplements
the AI_Construction_Vehicles.txt file with specific units to
purchase. See the AI_Construction_Units.txt file included for
more details.

Version 1.63:
1. Fixed - The AI was not matching class names correctly from the Vehicle
Construction file.

Version 1.62:
1. Fixed - The AI was not purchasing colonizing ships.
2. Changed - Put in opening screen from release Version.
3. Added - More details to AI Fleet order debug output.
4. Fixed - AI was not creating multiple designs which were of the same AI
Design Type (even if they had different names).
5. Fixed - Troops were not using their shields in ground combat.

Version 1.61:
1. Changed - The Default_Ai_Construction_Vehicles.txt file will now allow
for the design name or the design type. The term "Colonizer" is
till hard-coded to be evaluated to the needed type of colonizer.
When looking for the design to build, the game will look for the
latest design which matches the design name. If no match is found,
then the latest design which matches the design type will be located.
If neither is found, this purchase item will be skipped.
2. Added - Added an optional file called "DebugSettings.txt". This filed should
be placed in the SE4 directory and controls whether certain debug
setting are used in the game (if the file is not present all of the
debug settings are turned off). See the file for complete details.
