Improve tst_qdeclarativetextedit.

- Base on QDeclarativeDataTest to locate test data.
- Make small windows frameless to prevent errors from
  minimum size constraints of decorated windows on Windows.
- Add test messages printing the value of comparisons.
- Skip alignment tests if no reference image exists:

  Previously, the test would create an image file name
  "<testfile>-unknown-architecture", find out it does not
  exist, write out the 'actual' image under that name
  (clobbering the source directory) and compare to it,
  claiming success.

  The reference image name is now composed of platform and style
  name and the test is skipped if the file does not exist.
