fix typo
make request building referentially transparent
rename access to the RequestBuilder to 'underlying' as its more readable and sort of follows the same naming pattern as unfiltered (which models this in a similar way)
explicitly release external resources on shutdown for issue #58
set default scala version that is one of cross-built versions
Great. Something somewhere defaults to 2.10, just not completely. It's
easier to agree with it in this build's default (although, not ideal,
because now it becomes to easy to "fix" deprecation warnings by
breaking compatibility with 2.9.3, but we'll deal with that.)
restructure defaults, make ugly daemon thread stuff private
move internal defaults into defaults
don't share resources across clients, so that instances can be
independently created and shutdown
version bump
maybe this lift-json artifact will work for scala 2.9.3, who knows
update to ahc 1.7.16, adapt test to its new url building behavior. fixes #56
