[Plugin: Add Twitter, Facebook Like, Google plus one Social share] Plugin deactivation deletes optio

I think this is all that is needed:

/* Runs when plugin is activated */
register_activation_hook(__FILE__,’kc_twitter_facebook_install’);

/* Runs on plugin deactivation*/
register_deactivation_hook( __FILE__, ‘kc_twitter_facebook_remove’ );

/* Runs on plugin uninstall*/
register_uninstall_hook( __FILE__, ‘kc_twitter_facebook_uninstall’ );

function kc_twitter_facebook_install() {
/* Do Nothing */
}

function kc_twitter_facebook_remove() {
/* Do Nothing */
}

function kc_twitter_facebook_uninstall() {
/* Deletes the database field */
delete_option(‘twitter_facebook_share’);
}

Point noted. Will add to the next release. Thanks a lot for contributing.
