Create relevant immutable collections for 'Collections.singletonList', 'Collections.singletonSet', 'Collections.singletonMap', 'Collections.emptyList', 'Collections.emptySet', 'Collections.emptyMap'

The usage of some static methods listed in the title from `java.util.Collections` class in the project looks non-elegant. Create alternative immutable collections for: 'Collections.singletonList', 'Collections.singletonSet', 'Collections.singletonMap', 'Collections.emptyList', 'Collections.emptySet', 'Collections.emptyMap'

What about replacing 'org.takes.Scalar' with 'org.cactoos.Scalar' ?

[Cactoos project](https://github.com/yegor256/cactoos) already provides [org.cactoos.Scalar](https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/Scalar.java) which is similar to [org.takes.Scalar](https://github.com/yegor256/takes/blob/master/src/main/java/org/takes/Scalar.java). Why not just replacing usage of [org.takes.Scalar](https://github.com/yegor256/takes/blob/master/src/main/java/org/takes/Scalar.java) with [org.cactoos.Scalar](https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/Scalar.java) ?
