I fixed `urllib.urlencode` to `urlencode` in line 135

Fixing the cache key for both get and store methods

Can't believe this hasn't been in until now! Huh.

The media/upload endpoint is located on a different server :
upload.twitter.com.

It returns a unique result model called `Media` containing the
`media_id` and the image infos.

AttributeError: 'Response' object has no attribute 'status'

Requests handles this automatically for us

This will be True if the last result was cached.
Otherwise this will be False if the result was freshly
requested from the Twitter API servers.

Conflicts:
	tweepy/api.py

	modified:   tweepy/binder.py

added timeout to api constructor with default 60s, set timeout when creating HTTPConnection and HTTPSConnection in binder.py
	modified:   tweepy/api.py
	modified:   tweepy/binder.py

This is to avoid caching calls like rate_limit_status which shouldn't ever be cached.

Binder was modified to only cache when the flag is true.
