Additional fixes to AppDb and stable release

This commit is the first "stable" commit for the core content of
dtf, and corresponds to release v1.0.2 of dtf.  There are additional
bugfixes in the AppDb library that slipped through.
Stability fixes and fixed missing unframework

Minor changes to several modules, all of which are stability or
limited functionality tweaks.  Also, the `unframework` module was
missing from the previous 1.0.2 manifest.xml file.
