Port of wallet.sh to python (wallet.py).

Also included are minor edits to util.py to create a clean blockchain and add a parameter to gather_inputs to specify number of confirmations.

+# Does the following:
+#   a) creates 3 nodes, with an empty chain (no blocks).
+#   b) node0 mines a block
+#   c) node1 mines 101 blocks, so now nodes 0 and 1 have 50btc, node2 has none.

+#   e) node0 mines a block, collects the fee on the second transaction
+#   f) node1 mines 100 blocks, to mature node0's just-mined block
+#   g) check that node0 has 100-21, node2 has 21
+#   h) node0 should now have 2 unspent outputs;  send these to node2 via raw tx broadcast by node1
