Added the following three new iCart notice types:

• User is on the iCart main page
• User is browsing iCart extra pages
• User is browsing a specific iCart upcoming product

Added four new phrases.

Added in extra checks for all iCart notice types that generate a list of items, so that if there are no items the appropriate message is displayed instead of empty select lists.

Altered discriptions on two existing iCart notice types to improve the wording.
