Chinese warlords - make warlords prioritize their economic foci more

[BugBot3000]

My suggestion is to tweak the ai_will_do factors for eco trees a bit and tell the AI to not do air or naval branches because they don't use them anyway unless they have reached the industrial capacity to build up planes or a navy (which all of China even lacks tech for). Some screenshots from a game with some of the affected tags, SHX being dead here but a high candidate for this behaviour. Exempt from this behaviour are probably the western tags and Hunan due to the lack of air and navy trees to waste their time on or even a distinct eco tree that they could ignore. I'll tweak Yunnan a bit myself but they are not doing as bad from my experience. This is 1941:

• [x] GXC lost 6 civs and a single mil due to occupation but them being locked out of their eco tree because they didn't do it until 1940 is speaking for itself

• [x] Sichuan pretends to be doing ok but most factories were aquired due to foci in the last year

• [ ] Nanjing has some factories but not due to them doing things right they shouldn't really take the air and naval foci because the AI makes zero use out of those until they have both the tech and industrial capacity to build planes and ships

• [ ] Shanxi might be dead but you can somewhat tell how much they cared for their industrial base by checking their former provinces. I know from other games they love not touching a single focus of their eco tree unless there is really nothing else left.

Overall ideally make the AI lean slightly towards doing their eco tree together with their other branches and greatly increase the ai factors on foci that do give civvies or other extremely important eco buffs (up to you and your knowledge of your tag)

Added for SZC.

Assigning Fort for QIE.

might be a bit of a miscommunication from my side but with "warlords" I didn't mean QIE and FNG. although it wouldn't hurt either for them to get a better base eco earlier

Added more AI weights to Liangguang's tree, so that shouldn't happen anymore for GXC.

Archiving this stale suggestion, for now. It can be consulted in the future, if needed.
