v2.4.3.1 (Pre-release) - Burn build-up, seeding/mid-save fixes, taproot

Test build 2.4.3.1, on top of the 2.4.3.0 stable. A batch of burn fixes plus a couple of new things.

Burn

• The burn penalty now builds up as you spray instead of an instant -80%. An accidental brush or a slide onto the field costs only a small amount, giving you time to shut the sprayer off. Sustained spraying still reaches the full burn.
• Seeding with starter fertilizer no longer burns young crops.
• The burn penalty no longer sticks after you replant (clears on sow, cultivate or plough).
• The soil monitor now warns you before liming or manuring would scorch the crop.

Compaction

• Ploughing now relieves only a little compaction. A subsoiler is still the real fix.
• Oilseed radish and canola slowly ease compaction as they grow.

Other

• Fresh mid-save installs no longer start fields at 0/0/0/0.
• See & Spray buy option shows on every sprayer (from the 2.4.3.0 line).

How to test

• Drop the zip in your mods folder and load a save.
• Burn: lime or manure a fully grown crop and watch the penalty build up as you spray. Brushing the edge should cost very little.
• Mid-save: add the mod to an existing save and check fields start at sensible values, not zero.
• Please report anything odd in the issues.
