Bug 21877: Show authorized value description for withdrawn in checkout

Bug 21877: Show authorized value description for withdrawn in checkout

During checkout the withdrawn information is displayed in a message :
"Item has been withdrawn".

Like in other pages and like notforloan, we should display the withdrawn authorized value description.

This patch adds this display.
Add <span> so that translation does not change.
Also adds class 'co-withdrawn' (like in checkin 'ci-*' classes) to ease hidding this new information via CSS.

Test plan :
1) On a catalog with items.withdrawn defined with authorized values category WITHDRAWN
2) Define in WITHDRAWN an authorized values 1 with description 'dropped in trash'
3) Define in WITHDRAWN an authorized values 2 with description empty
4) Edit an item with withdrawn=1
5) Checkout this item => You see 'Item has been withdrawn (dropped in trash)'
6) Edit an item with withdrawn=2
7) Checkout this item => You see 'Item has been withdrawn'
