Update the TravisCI definition to just run quickCheck.

This is for the pull request integration. This way, we will get green/red indicators in the GitHub UI as to whether or not the proposed change passes the quick check, which is or initial pipeline stage.
Added an initial cut of a persistent registry of model objects.
Reworked the property handling of JavaReflectionUtil

- Replaced readProperty() and writeProperty() with methods to look up properties.
- Tightened up what is considered a getter or setter method (eg don't consider static methods).
Renamed a class.
Replaced some direct usages of IdentityFileResolver with factory methods

- GlobalScopeServices creates a default FileResolver instance.
- Use FileResolver.withNoBaseDir() and withBaseDir() to create new resolvers.
- Use TestFiles fixture to create resolvers in tests.
Moved ClasspathUtil and ClassLoaderFactory and impl to baseServices.
Moved some inner classes from PayloadSerializer to become top level classes
Added a super class for a couple of specs to share fixtures.
Added a ClassLoaderSpec that describes a ClassLoader structure in a way that allows the structure to be recreated in another process (e.g. in the tooling api provider in the client process).
Extracted a test utility class out of a spec.
Extracted ClassLoaderRegistry out of PayloadSerializer, to separate the serialization and the management of ClassLoaders.
Some c++ spec updates.
Changed to tooling API provider to use ClassLoaderSpec to represent details of a ClassLoader, instead of using a URL[].
Fix unit test on java 5.
Try another fix for broken unit test.
Reworked serialization in the tooling API provider to handle the case where the client action has references to object whose ClassLoader is not visible from the action ClassLoader.
Renamed class.
Fixed broken unit test.
Extracted an interface out of tooling API ClassLoaderRegistry and inject different implementations on the provider and daemon sides (they don't do anything different at this stage, but they will).
Next version is Gradle 1.9.
