Removed references to redundant DELPHIDABLIB and DELPHIDABLIB2006 environment variables.

* Removed reference to need to download DelphiDabbler library code.
* Expanded 3rd party code section re DelphiDabbler code and encryption unit.
* Revised GIFImage section re updated code.
* Removed binary files section.

Added required DelphiDabbler library code to project in Src/3rdParty directory so that the code no longer needs to be installed into in a pre-compiled package:
* PJStreamWrapper.pas from Stream Extension Classes project v3.0
* PJSysInfo.pas from System Information Unit project v3.2.1
* PJVersionInfo.pas from Version Information Component project v3.2.0
* PJWdwState.pas from Window State Components project v5.3.1

* Documented changes for release 3.4.6
* Fixed typo and errors.

Flagged a bug TODO entry as fixed.

Version numbers updated to 3.4.6.165.

Changed TDataBackupMgr to backup user database to a single file in the per-user application data folder rather than copying all files to a backup folder. Should fix bug #2898687.

* Rewrote TUserDBBackup as a sub class of new TFolderBackup.
* Now writes a file identifier of $DBAC to backup file to identify it as a user database backup.

Added new UFolderBackup unit. Class that can back up all text files in a folder into a single file.
