Update flo-webwallet.js

Browse Source 
- removed syncTransactions and readTransactions
- replace the above with listTransactions function set
- listTransactions(address) gets the latest  tx (1000 max)
- listTransactions.syncOld(address, initItem): use the initItem received by listTransaction or prevous .syncOld call. give the next old 1000 tx
- listTransaction.syncNew(address, lastItem): use lastItem received by listTransaction or previous .syncNew call). gives the new txs (1000 max) from last call
