Shortener-Plugin
A Shortener Plugin is an special plugin to use on Choqok::ShortenManager to shorten a Link, and derived from Choqok::Shortener class.
A Shortener plugin have to provide URL shortening, So, Just one function is needed to override:
QString shorten( const QString &url )
We will provide a way for plugin configuration just like other plugins, By using a KCModule plugin.
