Send accepted any amount parseFloat() read as above zero, so "1e-3",
"1abc" and an amount with a nonzero digit past the token's decimal places
reached ConfirmTx, which then refused them. isValidAmount() in
src/shared/txValidation.js is now the one check: Review and Max on Send
call it with the token's decimal places, and validateTransfer() calls it
for ConfirmTx, which now also refuses a zero amount and a token amount
with a nonzero digit past the token's places. Zeros past those places
are accepted, since the amount encoded for the transfer is the same.

Max fills in a token's balance, cut down to the 18 decimal places the
confirmation screen accepts, or for ETH the exact balance minus the fee
reserve the confirmation screen's balance check gates on. An ETH fee estimate
that finishes after the Send screen was left, or its address, holding,
recipient or amount changed, fills nothing in. The confirmation screen works a
max ETH amount out again from its own fee estimate and signs it with that
estimate's fee fields, so a fee that rose before signing cannot push amount
plus fee above the balance. validateTransfer() still gates every send, the
check that ETH covers a token send's fee included. Where there is nothing to
fill in, a flash message says why.
