#1218 Unused import warning when importing from try-except block

[Manuel Cerón]

PyDev warns me about an unused import when I import modules from a try-except block. For example:

try:
import json #marks unused import
except ImportError:
import simplejson as json #marks unused import

a = json.loads('"hello world"')

I also see this when a type is conditionally imported in an if-else block. For example:

import sys
if sys.platform == 'win32':
from platform import Windows as Platform
else:
from platform import Linux as Platform

print Platform().home_dir

Both imports in the if-else block have warnings. The first warning says "Unused import: Platform", the second says "Import redefinition: Platform".
