- a new --name option for "type summary add" lets you give a name to a summary
- a new --summary option for "frame variable" lets you bind a named summary to one or more variables
${var%s} now works for printing the value of 0-terminated CStrings
type format test case now tests for cascading
- this is disabled on GCC because GCC may end up stripping typedef chains, basically breaking cascading
new design for the FormatNavigator class
new template class CleanUp2 meant to support cleanup routines with 1 additional parameter beyond resource handle
