Visual Test Shell for BACnet SVN

Bug 3046835: don't throw on null buffer: size may be zero

Had wrong enumeration for event state filter

Set defaults for
- Script editor insert template file
- EPICS directory to location of sample (.docs)

Convert property value to upper case before comparing (bug introduced when enumeration strings were aligned with the BACnet standard)

Eliminated CHeckEPICSCons dialog, which has been obsolete for some time. This data is shown in the EPICS View pane

CR 3010449. Use GetTempPath to get appropriate location for EPICS error temporary file
(Reinserting changes from version 1.68 which were obliterated by version 1.69)

Added return type specification VTSAny& to operator=() and
return type specification VTSAnyList& to operator=()

BACnet.hpp
Added return type specification BACnetAPDUEncoder& to operator=()

BACnet.cpp
Added return type specification to static int ix = 0;

Added comma after "square-inches", //115 so that the rest of etable etEU
starting with "square-centimeters", //116 is no longer index off-by-one.

Added constructor initialization of pDeviceObject(NULL) in PICSdb::PICSdb()

Added "ANSI X3.4/UTF-8" and also a form with alternative whitespace
"ANSI X3.4 / UTF-8" to Charsets[]

Added "Unconfirmed Response Fail Time"
to FailTimes[] (requires increase in MAX_FAIL_TIMES to 8 in VTS.h)

Issue tperror("Invalid List of DevObjPropReferences",true)
if ParseDevObjPropReferences returns (TRUE == reffail)

If supports DM-ATS-A (but not for DM-MTS-A), also requires
Time_Synchronization_Recipients present & WRITABLE.
