Add "should" prefix for method names

```
I prefer "spec" notation for my test names:

public function should_return_correct_values() : void {}

Currently only "test" prefix is supported.

Workaround is to use [Test] metatag with -keep-as3-metadata+=Test compiler
option.

[Test]
public function should_return_correct_values() : void {}

Suggested fix:

Expose static array with prefixes.
```

No file or test is named in the issue. Start by locating the existing handling for the `test` method prefix and the proposed static prefix configuration; use the `should_return_correct_values` example and the `[Test]` metadata workaround to verify the expected behavior.
