* Drop support for Ruby 1.9.2, which no-one should be using any more.
* Constraint gem versions for Ruby 1.9.3
* Drop support for Ruby 1.8.7. Many dependencies have dropped support for it.
* Remove conditionals checking for Ruby 1.8.7
* Document Ruby version dependency
Spins up a proxy server in a separate process, runs a few requests
through it with each adapter to verify that both proxy support and basic
authentication take effect.
The HTTP server is now started in a subprocess, not a thread. Running it
in a Ruby thread had all sorts of problems on different Rubies, such as
random failures on Rubinius.
The new script also avoids starting the HTTP server if not needed, e.g.
if filtering arguments have been used to select only the non-adapter tests.
The script dumps the server log to stdout if any tests failed on Travis.
Avoids auto-starting the debugger because it blocks for input in Rubinius

The error was:
NameError: uninitialized constant OpenSSL::OPENSSL_VERSION
It seems to choke when "openssl" is required in a thread.
Not always, though.
