Duplicates detected in spp, removed, by Tuuli
Update spp files
Update groups files

Groups were updated according to new spp files (birds updated).

Groupfiles were updated as the number of bird files changes. The
new group code is a combination of species code + weight, as
follows:

Species code: (Note: I now reserved the numbers for all species
groups, although not included in the analyses).

Amphibians (1), Birds (2), Corals (3), Mammals (4),
Mangroves (5), Marine_Fish (6), Reptiles (7), Seagrasses and
Seasnakes (8), Ecoregions (9)

Weight:

as in weighted spp based in IUCN vategory (reclassifies by
C-BIG), expect 9 for ecoregion weights (varies between 10 and
40 in analyses).

An example: the group for a least concern bird would be 21.
Update dat-files for 01-08

[vmat] section header was missing and groups files paths had a
wrong "../" prefix.
Update all bats to use zig4.exe

Previously all bat-file calls were using older zig3.exe
Remove load precooked vmat options from 01-08 dat files

Preloading a vmat file that does not exist will cause a fatal error.
This behaviour is intentional, so disable loading at this initial
stage.

THIS HAS TO BE TURNED ON LATER, THOUGH.
