Fixed fixme for ajax auto-completer for showcart screen of order entry process.
Currently call_fieldlookup2 is used for the product lookup, auto completer is not supported via call_fieldlookup2 and it open a window instead of layered lookup.
Need to use htmlTemplate.lookup field for the product lookup. Also removed the FIXME comment.
The FIXME issue was fixed in OFBIZ-4646, Now its working fine.
