The beginnings of auto-echo-add:

- SBBSecho will now maintain a file called the Bad Area File
  (default name is data/badarea.lst), in BACKBONE.NA format
- This file is suitable for importing in SCFG->Message Areas now, but expect
  some automation in the near future
- To get area descriptions (not just echo tags) in the Bad Area File, be sure
  to configure at least one "Additional EchoList" to point a comprehensive echo
  list (e.g. BACKBONE.NA or similar)
- SBBSecho will automatically add new areas (when new messages are received for
  msg areas you don't carry) or remove areas that you start to carry - no sysop
  maintenance of this file should be needed. And the file does not have to be
  deleted after being imported (e.g. with SCFG).
- SBBSecho does not (and may never) actually modify your Synchronet Message
  Areas configuration directly, that is yet to be determined

Another new feature: Area File (areas.bbs) backups:
- Whenever the Area File is modified via AreaFix, the current file is backed
  up  (e.g. areas.0.bbs, etc.)
- This feature can be tweaked or disabled via the AreaFileBackups key in
  sbbsecho.ini (not yet in echocfg), default backup level is 100

* Numerous EchoCfg help text updates.
* Some minor terminology updates (e.g. AREAS.BBS->areas.bbs, Areafix->AreaFix).
* Incremented SBBSecho version from 3.00 to 3.01.
