[Kde-bindings] String is no longer Enumerable on Ruby 1.9.1

[airh2002 at oak.dti.ne.jp]

String is no longer Enumerable on Ruby 1.9.1, and String#each is
nonexistent.

For QtRuby, I find String#each usage on rbqtapi.
I suppose below:

145c145
< candidates.each do |candidate|
---
> candidates.send(RUBY_VERSION >= '1.9.0'? :each_line : :each) do
|candidate|

This is useful for before 1.8.x and after 1.9.x.
