function FileValidatorTest::testFileValidateImageResolution in SimpleTest 7

This ensures the resolution of a specific file is within bounds. The image will be resized if it's too large.

This provides SimpleTests for the core file handling functionality. These include FileValidateTest and FileSaveTest.
