ch04: Fix 'key-to-address-ecc-example' 
The 'pybitcointools' library is deprecated. Vitalik mentions using the
fork from 'primal100'. This updates the code sample which is currently
broken, to use the Python package for that fork.

Runs all good now.

Update key-to-address-ecc-example.py 
If line#24 use 'wif_compressed', it will produce a wrong Key (WIF-Compressed) started with 2.

So there should be 'wif', unless :
wif_compressed_private_key = bitcoin.encode_privkey(
    bitcoin.decode_privkey(private_key, 'hex'), 'wif_compressed')
This is also right. 
However, use the 'compressed_private_key' and 'wif_compressed' is wrong.

9504d804e0 Stop using numeric_limits for the constant "255", and fix a bug. 
The bug is that `x % 255` is not quite the same thing as `x % 256`;
but `x & 255` is.

The stylistic issue is that `numeric_limits<uint8_t>::max()` is a
very verbose way of spelling `255`.

Update key-to-address-ecc-example.py 
The code is very possible to miss a leading '0'.
E.g:
Private Key (hex) is: 57c003d31cca32f79a22e70334fff37875617e89c04d2746b5efc22067ccb8fd
Before: Compressed Public Key (hex) is: 03 8f0de2360796ae0fe17f1a2b0be30af6fb45eccc4a1c7afb5ebea21d041b6e0
After: Compressed Public Key (hex) is: 03 08f0de2360796ae0fe17f1a2b0be30af6fb45eccc4a1c7afb5ebea21d041b6e0

The bug is in the pybitcointools, but it is not updated, we can only repair it ourselves.

Update hash_example.py 
As input and hash are inbuilt functions, so I'd suggest using other names for variables.
here is output from python interpreter.

>>> hash
<built-in function hash>
>>> input
<built-in function input>

`from __future__ import print_function` to bring the print function from Python 3 into Python 2.6 and 2.7.

Properly deals with comma separated values in print() function.
