Bug 9824: Followup for removing filter

Adds allbaskets parameter to GetBasketsInfosByBookseller. (Only used in booksellers.pl now)
Normally, all 'active' baskets are shown. With allbaskets=1 all baskets :)
In the template I had to rename a loop var supplier to supplier1 to resolve
name conflict between template vars.
In the template I added the string: Cancel filter.
Note that this string is already translated:
msgid "Cancel filter"
msgstr ""
Hope this helps.

Undoing the filter works and I checked that the string gets
translated with the po files in current master.
So this is almost perfect, only we can't apply the filters
again and the link remains 'cancel' when we already did.
Sending a follow-up trying to fix this.
