Bump visibility of Spring Integration

As "integration" is a frequent term in a description, the Spring
Integration is shadowed by other entries unless its weight is increased.

This commits make sure that integration shows up first when that term is
used, slightly reducing the weight of Thymeleaf in the process.

Closes gh-581
