Log Message:
devel/ruby-simpleidn: added simpleidn-0.0.9 gem as ruby-simpleidn-0.0.9.

This gem is required by forthcoming twitter-text-simpleidn-3.0.0.0 gem,
a forked version of twitter-text without libIDN dependency.

Simpleidn gem allows easy conversion from punycode ACE strings to
unicode UTF-8 strings and visa versa.
The implementation is heavily based on the RFC3492 C example
implementation but simplified since it does not preserve case.
