Changing connect and response timeout.

In bad network conditions and where switches often occur between 2G and
3G the timeout of 20s is too short.

Setting this timeout to 60 seconds will improve functionality in bad conditions
while it will not affect functionality in good networks. This change also aligns
the timeouts with the timeouts used by the Browser (Connection.java).
