[plugin Oi Frontend Profile] i18n missing string

Hello,

The string “Username” is not correctly associated with the plugin domain.

Line 169 is currently :
<?=oinput(array('key'=>'user_login','before'=>__('Username'),'disabled'=>true,'value'=>esc_attr($profileuser->user_login),'hint'=>__('Usernames cannot be changed.','oifrontendprofile'),))?>

It should be
<?=oinput(array('key'=>'user_login','before'=>__('Username', 'oifrontendprofile'),'disabled'=>true,'value'=>esc_attr($profileuser->user_login),'hint'=>__('Usernames cannot be changed.','oifrontendprofile'),))?>

By the way, if you are interested, I translated your plugin to French.

Thank you.
