Description

Currently it's only possible to compare a single CharSequence per is(Not)Blank/is(Not)Empty call.

This should be changed to support multiple CharSequences in a single call.

if(StringUtils.isNotBlank(foo) && StringUtils.isNotBlank(bar) && ...)

could be changed to

if(StringUtils.isNotBlank(foo, bar, ...)

As there are two possible ways to combine the results (AND and OR), it'd be necessary to create multiple methods.

isAnyBlank(CharSequence... cs)
isNoneBlank(CharSequence... cs)
isAnyEmpty(CharSequence... cs)
isNoneEmpty(CharSequence... cs)

I could implement those methods and contribute them via github if there is any interest from project's side.
