Refactor:

- Simplified receive/load to only use xhr's onload/onRSC. There's no
  advantage in using the RSC event.
Adapters added:

- Enabled Hijax adapters to add interception functionality for legacy
  and shitty libraries
- Added adapter for jQuery 1.3.2
- Added integration tests for jQuery 1.3.2 and 2.1.1
