Bug fixes and improvements for 2nd Dawn

Unfortunately, the update will make the current games unplayable. Please finish the games by then or wait to update until you have finished your games. Fixed the following problems: - AI chooses a warp portal deployment, even if there is already a warp portal in the sector. - Diplomacy through Warpportal not possible. - Draco can be peacefully on a sector with Guardians. - There is one 2 victory point reward piece too few in the game - 2 Monolith and 1 Orbital Discovery too many in play - The GCDS only has +1 instead of +2 computers - 6 does not apply to ships with shields - It is not possible to influence sectors from captured ships. - Orbital Discovery is missing 2 material for the player - Game sometimes crashes towards the end. (Could occur if a player's influence bar was completely empty, or completely full in the digital version). - Warpportal Discovery by Ancient Labs are not placed on the player's starting sector. - Discovery with 3 money, 2 science and 2 material is missing. - Warpportals are not optional. - Game crashes if you choose a population marker on an expanded universal planet for which you have not researched the technology. - Alternate blueprints are now available.
