Visual Test Shell for BACnet SVN

Add write-back test option to EPICS generator

Bug 322: add Match method to BACnetAddr. Refactor Match functions for all classes.

Read latest version from http://vts.sourceforge.net/vtsversion.txt once a week, show update available

Eliminate duplicate resource IDs, renumbering as needed. This fixes the MRU for workspace files.

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

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

- Ease initial configuration: guide first-timer (or New Workspace) through Device, Port, and Name dialogs.
- Revise some annoying initial values (useless list columns, window positions)
- Add executor to do device discovery using Who-Is and ReadProperty (Tools menu)
- Add executor to read properties and generate the object-list section of an EPICS (Tools menu)

- Add user preference for EPICS editor (default Notepad.exe)
- Save selected EPICS file even if it has errors, else the EDIT button won't work
- Include ALL EPICS-listed properties in read-object scripts (formerly only those with non-? values)

Refactor BackupRestoreExecutor and InconsistentParsExecutor, moving common code to new parent class SendReceiveExecutor.

Device tree: sort object-type and property-ID controls, simplify numeric type and property entry
