Purpose of change

This allows making generic weak mixed alcohol by watering down strong alcohol, letting you basically make grog without actually bothering to write up a separate comestible just for it.

Describe the solution

Added an alternative recipe for weak mixed alcohol combining 7 units of relevant strong alcohol (250 ml) to 4 clean water (1 L), producing 5 units (1.25 L) of weak mixed alcohol.

Compare the recipes for ethanol and denatured alcohol asking for 14 units of strong mixed alcohol or 10 units of weak mixed alcohol.

Describe alternatives you've considered

1. Adding grog anyway for the funny.
2. "Kerosene, propylene glycol, artificial sweeteners, sulphuric acid, rum, acetone, red dye no. 2, scumm, alxe grease, battery acid, and/or pepperoni."

Testing

1. Checked affected file for syntax and lint errors.
2. Ported over to playthrough build and load-tested.

Additional context

Ayy, 4:1 ratio works out perfectly for bonus historical points:

 In 1740, to minimise the subsequent illness, drunkenness, and disciplinary problems, British Vice-Admiral Edward Vernon ordered that the daily rum issue of one-half imperial pint (284 ml) of rum be mixed with one imperial quart (1,100 ml) of water, a water-to-rum ratio of 4:1, with half issued before noon and the remainder after the end of the working day.
