Visual Test Shell for BACnet SVN

Fig for Bug321: MI stored only 8 bits for present-value and number-of-states, while object table specified 16. Similar error in MO had 8 bits for feedback-value.

Gussy up EPICS generator: include property-list properties. Show object-types-supported and services-supported text.

Had = instead of == in ReadFloat. Someday I will get fed up enough to fix all the lameness that keeps us at warning level 3 instead of 4...

Accept special Real and Double values NaN, +inf and -inf in EPICS, scripts, and dialogs.
Centralize conversion to/from ASCII and comparison logic for consistent display.
Update script templates with current error classes and codes.

- Fix bug in parsing tag values 15 and above (forgot to skip the extension byte)
- Improve script exception handling to show plausible line numbers more often
- Update script Expect processing to accept bitstrings in "modern" [] format (leaving legacy as well)
- Update Date entry so that omission of day-of-week CALCULATES it, rather than assuming wildcard. If you want wildcard, type a *

Correct bug in versioning of the VTS document (.cfg file) introduced in svn 977 due to misunderstanding of CArchive.
Should be backward compatible with .cfg files created or modified with code prior to svn 977.

Add event notification parameters for new eventTypes to BACnet decoding

Clean up and finish support for max-segments-accepted in Confirmed-Request header:
- keyword MAXSEGS in scripts
- add to Device edit and persisted data

Fix crash/exception in DateTime value dialog: CTime::GetLocalTm no longer (as of 2005) allows a NULL argument

A few more tweaks to preserve compatibility with VC++ 6.0.
