Also display next to quantity field

Hi,

I installed this plugin and it works beautifully.
Right now it displays the UM right next to the price.

I would like to suggest the following:
1. Next to the price add a slash before so it displays $99 / kg instead of $99 kg.
2. Add the unit of measure behind the quantity field. You could even use an :after tag to do that, so the quantity field becomes: [ 1 kg] or [ 1 ] kg, instead of just [ 1 ].

Keep up the great work!
