Game version 0.95.192 released

Notable changes:

• Modified AI behavior to encourage it to attack more often. [Issue #866]
• Reduced the total amount of attack fleets to 1 for each 10 planets.
• Reduced the time between attacks to 5, 3 and 1 days depending on difficulty levels (easy -> hard)
• Changed the way fleets are upgraded by always upgrading the strongest fleets first which allows them to attack earlier.
• Changed how AI selects its next target. Based on the relation with other races, it may chose with probability 60% the most hated enemy, 15% of the second-most hated enemy and 25% any of the rest. After this, it choses the weakest known planet 60% of the time, the second weakest 15% of the time and any of the rest planets with 25% of the time.
• Fixed the mission script for meeting with Admiral Thulen at the end of level 1 triggering the Garthog attack too early and out-of-bounds if the player waited at the border. Now you need to meet with the Admiral inside the accessible area. [Issue #892]
