TERMINOLOGY:
-- "slot" = A particular combination of case/number.
Example slot names for nouns are "voc_s" (vocative singular) and
"gen_p" (genitive plural). Each slot is filled with zero or more forms.
-- "form" = The declined German form representing the value of a given slot.
-- "lemma" = The dictionary form of a given German term. Generally the nominative
masculine singular, but may occasionally be another form if the nominative
masculine singular is missing.

FIXME:
1. Qualifiers in genders should appear as footnotes on the articles.
2. Support notation like <g:f> on feminine/diminutive/masculine, e.g. used for [[Gespons]] (neuter with the meaning
"wife", masculine with the meaning "husband").
3. Fix CSS gender-specific class in table.
4. Support adjectival nouns and adjective-noun combinations.
5. Allow period and comma in forms e.g. for [[Eigent.-Whg.]], [[Eigt.-Whg.]] (using a backslash). (DONE)
6. Allow embedded links in genitive/plural/feminine/diminutive/masculine specs, e.g. 'f=![[weiblich]]er Geschäftspartner'.
7. Add 'prop' indicator to indicate proper nouns and suppress the indefinite article.

Propagate `property` ("gender" or "number") from nouns to adjacent adjectives. We proceed as follows:
1. We assume the properties in question are already set on all nouns. This should happen
in set_defaults_and_check_bad_indicators().
2. We first propagate properties upwards and sideways. We recurse downwards from the top.
When we encounter a multiword spec, we proceed left to right looking for a noun.
When we find a noun, we fetch its property (recursing if the noun is an alternant),
and propagate it to any adjectives to its left, up to the next noun to the left.
When we have processed the last noun, we also propagate its property value to any
adjectives to the right (to handle e.g. [[пустальга звычайная]] "common kestrel", where
the adjective польовий should inherit the 'animal' animacy of лунь). Finally, we set
the property value for the multiword spec itself by combining all the non-nil
properties of the individual elements. If all non-nil properties have the same value,
the result is that value, otherwise it is `mixed_value` (which is "mixed" for animacy
and gender, but "both" for number).
3. When we encounter an alternant spec in this process, we recursively process each
alternant (which is a multiword spec) using the previous step, and combine any
non-nil properties we encounter the same way as for multiword specs.
4. The effect of steps 2 and 3 is to set the property of each alternant and multiword
spec based on its children or its neighbors.
