Project Filelist for OpenVAS

This is the second beta version of the upcoming 6.0 release of the OpenVAS
Manager. It is the central management service between the actual security
scanners and various user clients.

This release continues the efforts towards PostgreSQL support and support of
multiple scanners. It also introduces support for a "Guest" role and for
associating ESXi credentials with targets, along with a number of smaller
improvements and code cleanup.

Many thanks to everyone who has contributed to this release:
Hani Benhabiles, Matthew Mundell, Timo Pollmeier, Jan-Oliver Wagner and Michael
Wiegand.

Main changes since 6.0+beta1 series:
* Further steps towards alternative use of PostgreSQL as database backend
  instead of SQLite3. The PostgreSQL support does not yet cover all of the
  OpenVAS Manager functionalities.
* Further steps for Scanner Management.
* Support for a "Guest" role has been added.
* Support for associating ESXi credentials with targets has been added.
* The get_results command now behaves more consistent with other get_... OMP
  commands.
* The task name is now included in more report formats.
* The value of the NVT tag "affected" is now included in more report formats.
* GPLv2+ licence notices now contain the exact wording suggested by the Free
  Software Foundation.
* Code cleanups.
