- Now using ${var} as the summary for an aggregate type will produce "name-of-type @ object-location" instead of giving an error

Browse Source 
e.g. you may get "foo_class @ 0x123456" when typing "type summary add -f ${var} foo_class"
- Added a new special formatting token %T for summaries. This shows the type of the object.
  Using it, the new "type @ location" summary could be manually generated by writing ${var%T} @ ${var%L}
- Bits and pieces required to support "frame variable array[n-m]"
  The feature is not enabled yet because some additional design and support code is required, but the basics
  are getting there
- Fixed a potential issue where a ValueObjectSyntheticFilter was not holding on to its SyntheticChildrenSP
  Because of the way VOSF are being built now, this has never been an actual issue, but it is still sensible for
  a VOSF to hold on to the SyntheticChildrenSP as well as to its FrontEnd
