issues found in walkthrough of CCM5 instance

1. repo is still reporting that its in state "scanning", with associated banner on all FE pages, even when scanning is (presumably) complete.
2. in UnitTestCCBase, file extensions not appearing in chart dropdown, or code metrics report
3. handling of binary files - build.xml, .java files, other obviously textual files considered binaries, so no diffing available
4. for binary file, on File history page, RAW link -> 404 (missing revision ID)
5. NPE viewing http://clearcase:6060/foo/browse/ClearCase/vob/fe_ucm/FE-ccdev/src/java/com/cenqua/fisheye/ctl/Run.java?r=/main/FE_1_Int/2
