* address mini-map concerns in #8924
This is meant as a lightweight replacement for all_children_range in cases where the iterator doesn't need to be stored (most cases). It has several advantages:
First, it avoids the custom iterator classes, making the code easier to read. It also means it should be composable with STL ranges in C++20. Further, you no longer get a mutable reference on a const config. Finally, it means intellisense can properly display the key/cfg types in a structured binding. When unpacking `config::any_child`, for some reason it shows up as a key/value copy instead of reference...
This makes a lot more sense given how forgotten everything before the fall is by the time of UtBS. 300 AF is small enough for a few elves to remember the times before. 1000 AF is more sensible in my opinion.
Skeletal Dragon saw very major buffs in #8541, which causes some concern about rebalancing and UMC. This reduces their stats closer to 1.18, though still moderately stronger.
Was only used in two places, one of which was as the implementation of the version that took a vector. All the same arguments were accepted by both. Also use list initialization for the other overloads.
outside_area checks that the point is within the given rect reduced by hex_size(). Since that's the size of a location rect, the adjustment meant that a hex can't protrude outside the map area. This simplifies the logic using rect math instead of point math.
reuse partially 1493faeaee but don't remove check cfg. Thanks to @Pentarctagon
if for example the ability filter searches for the value of 'active_on' in an ability 'leadership' then the false value will be returned because active_on is not an attribute usable in [leadership]
on the other hand if the ability is of type 'dummy' its encoding remaining at the discretion of the UMC developer, the checking can be done normally
