Issue #6: required file in scripts

A solution to the issue #6, the test will only search for required file starting by './' or '/' and match with file specified in component.json among script, json, and file.
also you should move the readFile into `ComponentHint.prototype.loadComponentData`
this will allow other tests to use them as well
