QoL for TWoTS

This mod contains bunch of small bug fixes and adjustments for original TWoTS vesion 2.51.2.

Main changes:

Research:

• All research tree of original TWoTS left unchanged but it has now small QoL changes - researching of live medics could help you now unlocks same additional research TWoTS topics, what early requires capture live aliens or their corpses. For example: if medic unlocks UFOpaedia article about deep one corpse autopsy it's unlock aqua plastics research too. If medic unlock live deep one it's unlock molectronics. The main goal of this is help players progress in game if they had no luck getting necessary corpses or live aliens. To avoid unlocking end game content fast with medic's bonuses, UFOpaedia articles about some aliens and corpses only available by researching middle or endgame medics only. Of course you could play old fashion way and capture or kill necessary aliens by yourself. Don't forget what bonus UFOpaedia articles which pops up when live medic researched is random and to get info about needed alien or corpse as soon as possible you need research rest of them manually or hunt for live medics as much as you can to raise you chance unlock needed article fast. About live aliens and their corpses - if medic unlocks article about alien corpse and you have started it as separate research in laboratory as another project, this project will consider as complete and will be removed from the list. This prevent double researches of content which no longer actual. Same for live terrorist units. Only exceptions is live soldiers, squad leaders and other ranked aliens, their live bodies still could be researched apart from medic's bonus.

Items:

• Stats of knife and vibroknife has swapped. This will satisfy UFOpaedia articles. Original TWoTS knives could one shot lobsterman on superhuman difficulty but vibroknife like mosquito bite for them.
• Sonic autogun has now snap shot for chance of reaction fire.

Cosmetics and small bug fixes:

• Production of acid torpedoes now require finishing heavy aquatic weapons research.
• Researching of live paladin will show UFOpaedia article about his armor, which logical, because it's now possible to repair.
• Added missing research points for carcharodon corpses. Their corpses could now unlock alien containment too.
