Prettied up the makefile slightly
Use native setImmediate which was added in 0.10.
Replace *all* node includes with browser equivalents
Added some more request headers on outgoing PUTs
Read files in raw buffers instead of binary strings
Reuse a body cleaner instead of redefining it for every test
Run every test in the test folder, not only the unit tests.
Image identifier header does not contain a dash between 'image' and 'identifier'
Added integration test (needs configuration customization etc)
