Multiple FG3 Improvements

[IllianiCBT]

• Added better logging to assist in narrowing down FG3 oddities and to make it easier to verify everything is working as intended.
• Added checks to ensure planetary and weather conditions are enabled before we declare certain unit types as unsuited for the scenario.
• Added fallback generation, so that if we request a unit type that cannot survive in the environment it uses a fallback unit type instead. This is Infantry (Conventional or BA) -> Tank -> Mek. In this way if we try to generate infantry in an environment they cannot survive, we will attempt to spawn a tank instead, if that also can't survive we spawn a Mek. Tanks skip the infantry stage. While this may result in some unusual spawning (for example, reinforcements from a tank base might turn up as meks if the scenario is in a tornado), it will better avoid 0-unit forces. This has been written to work with the 'infantry use survival gear' changes that were made a while ago.
• Corrected a number of scenarios so that they correctly contribute to BV and to fix formatting errors.
• Corrected Heavy Recon Evasion's objectives
• Fixed the 'fleet of DropShips' bug
• Simplified bidding reporting, so that it's less cluttered
• Fixed the Batchall dialog to trigger correctly. Now, while it may trigger while the campaign is still in transit, it will more consistently trigger. There were edge cases that could cause the dialog to never trigger.
