supplement 2.29 -- Useful Ruby enhancements

Some simple Ruby extensions.

The original motivation was my conviction that a language that has a Numeric#nonzero? method induces a programming style that as well demands for a String#notempty? method.

These are methods on standard classes that didn't manage to become part of the Ruby interpreter. (Although, some did in the meantime.)

They are all very small, most of them have less than 15 lines of code. So they would not be a weight in the Ruby interpreter but it is very difficult to convince a majority that they belong there.

The methods won't be useful for everybody but some programmers may like to make them part of their programming style.

If you like to get taunted, then go to the Ruby mailing list and propose one of them to be included into the Ruby standard.
