Fixed issue 19 by jimboman77: https://github.com/spesmilo/electrum/issues/19

"Right now the only check thats being done is making sure that the length isn't 0, ie something is being entered before the send button becomes clickable."

Also check that entered amount is <= btc_balance before enabling send button.
