Pull #3263: corrected alphabetical order of the checks

[f05fk]

The "Checks" page lists the available checks in alphabetical order and even says that it does. Therefore I corrected the order of some checks, because they have not been in the right place.

Current coverage is 100%

Merging #3263 into master will not change coverage

When we sort checks on other pages, we sort them ignoring case. We should probably continue that type of sorting here.
See https://github.com/checkstyle/checkstyle/blob/master/src/test/java/com/puppycrawl/tools/checkstyle/internal/XDocsPagesTest.java#L283-L287

Here are some other changes based on that type of sorting:
JavaNCSS should come after JavadocVariable, NPathComplexity should come after NoWhitespaceBefore, NonEmptyAtclauseDescription should come after NoLineWrap (not NoWhitespaceBefore), TypeName should come after TypecastParenPad.

Ok. Good argument. I also find it more natural to sort case-insensitive but I tried to stick with the existing case-sensitive sorting in my first attempt. I'll apply the suggested changes.
