boto.config.getint doesn't work as expected in python3.

[zhouxiaojian1985]

my boto version is boto-2.38.0.

python2.7.10

>>> import boto
>>> boto.config.add_section('Boto')
>>> boto.config.set('Boto', 'http_socket_timeout', '10')
>>> boto.config.get('Boto', 'http_socket_timeout')
'10'
>>> boto.config.getint('Boto', 'http_socket_timeout')
10

python3.4.3:

>>> import boto
>>> boto.config.add_section('Boto')
>>> boto.config.set('Boto', 'http_socket_timeout', '10')
>>> boto.config.get('Boto', 'http_socket_timeout')
'10'
>>> boto.config.getint('Boto', 'http_socket_timeout')
0

We should expect 10 in python3.
