Test frames remove anchor body

This pull request fixes #220 . Deprecated use of "anchorBody" interfaces were causing compilation errors in the debug build.  Release builds compiled because these errors were contained in assert expression that were only compiled in debug builds. This PR specifically:

1. Removes all outdated usage of getAnchorBody() and isAnchoredToBody() in testFrames
2. Removes all usage of assert, using ASSERT instead throughout testFrames.
3. Fixes a transposition bug in FixedFrames transform calculations.
Right now, it's hard to distinguish between "new tabs" and "preexisting tabs". I don't think it's worthwhile for people to stress about spaces until I convert all tabs to spaces. I'll do this now and submit a PR, now that the two big PR's are in.
