Update GitTip

Not expecting much to come of this, but it's an interesting experiment.
Allow to pass the `adapter` option in globals, pass it to HTTPI when performing SOAP calls.

There is no tests yet.
Added tests for specifying adapter in globals

Conflicts:
	spec/savon/options_spec.rb
Use wasabi ~> 3.3.0
Bump version to 2.5.0
Add basic WS-Addressing support (refs savonrb/savon#409)
Add uuid gem to gemspec dependencies
Switch around ruby versions in .travis.yml

There has been some churn in how you specify rubinius and jruby for
rvm on travis-ci lately and I'm hoping that specifying

"rbx-2" and "jruby"

will clear this up.
Add example in CHANGELOG for per-client http adapter
Merge pull request #571 from alexanderk23/issue-409

Add basic WS-Addressing support (closes #409)
Attempt to deflake this test for jruby

This is the last jruby failure I've seen recently. Filing an issue for HTTPI
to tag timeout errors so we can stop adding to this madness.
JRuby is no longer an allowed failure

Sweet suite success
Merge remote-tracking branch 'upstream/master'
