kgio-monkey 0.3.0 - small improvements

Add external session cache support for:
* tdb - http://bogomips.org/ruby-tdb/
* dalli - http://rubygems.org/gems/dalli
* memcached - http://rubygems.org/gems/memcached

For newer versions of OpenSSL, this adds a
Kgio::SSL::OP_NO_COMPRESSION flag to disable compression support
on a per-context basis.  This is interchangeable with the
OpenSSL::SSL::OP_NO_COMPRESSION flag (to be) introduced in Ruby
1.9.3
