Create test cases for multiple games

[fmahnke]

Create test cases comparing game images against known, correct reference strings. The test pass rate can be used to track the progress of the translation project as a whole.

• Add initial tests for several games.
• Add known, correct reference strings to the test suite.
• Remove images with no text to translate, and corresponding reference strings.
  De-duplicate images in test suite. (see Decide action for duplicated images in test suite #13)

#3 completes the first item: adding test stubs.

I'll pick up creating correct text references for 7thelnard through bof2, and @fmahnke will try to take up darkhalf through rudra
(alphabetically speaking)

Should we need to dedupe if we're concerned about hardware noise?
