AddressHistory API: query option 'latest'

Browse Source 
- using latest option will query the latest 1000 (MAX_ITEM_LIMIT) of the address
- Allowed values:
0 or false => false (DEFAULT)
1 or true => true
*nothing* => true (ie, just leave the query as ?latest)

- Address history API now also gives initItem (oldest tx in itemlist). initList is undefined if no confirmed tx available in item list
