Docs: Inconsistent wording and referencing in help text

1: _.reject help text states that it is the opposite of _.filter. _.filter help text does not reference reject at all.

It would have been helpful to me on many occasions to be able to find one by seeing the other.

2: Example:

• _.reject says "The opposite of filter"
• _.unescape says " The inverse of escape"

I feel like they should both say opposite or inverse.
