consider Cud option for vert-indent on cliking treeview nodes

[Alexey-T]

you can take abs(N) for N<0. to be simple.

cudax_lib gives the API get_opt.

Done.

Thanks for the tip, I was not aware of this option

[Alexey-T]

what if that option is missed in config? you will get 0 and use 0 indent?

2) option allows valie 100 !

for big values N, where abs(N)>=100, make centering vertically

but plugin won't handle 100. Let's revert this - use 5 fixed value. Don't read the opt.

I think it will fallback on the default value?

ok, reverting
