v0.6.9 AWSS3 EOFError fix & Debug improvements

Fix JuliaCloud/AWSS3.jl#26 -- EOFError doing S3 PUT to Ceph via nginx.

• Reinstate yield() after @async writebody(...) in request(::Type{StreamLayer}, ...
• See fa6b206

Debug message improvements:

• Add timestamps to DEBUG_LEVEL > 0 messages
• Print time since last read activity in show(::IO, ::Connection)
• Enable DebugLayer (aka verbose=3) when DEBUG_LEVEL >= 3

Fix for query= option in request(::Client, …)

v0.6.8 new options: idle_timeout=, connect_timeout= and proxy=

New HTTP.request options:

• idle_timeout, No. of sconds to maintain connection after last transaction.
• connect_timeout, No. of seconds to wait for TCP connection to be established.
• proxy=, HTTP and HTTPS proxying (not yet tested in the real world). See #218
