* removed pol_distance/inrange* functions
replaced lastxyz with Pos4d
* replaced WorldIterator::InVisualRange with InMaxVisualRange returning
all objects in maximum update range. Adapted each caller, they now have
to check in_visual_range
Multis should now be send to clients with its footprint in mind.
added testscript for boat moving in/out of range
* removed non pos InRange/InBox functions
gamestate.update_range doesnt need to be a Vector, renamed
* corrected send_action_to_inrange
* replaced clip methods with general numeric type clamp function
* added Range2d constructor with radius
* splitted update_range. chr has now a los_size (how far can it see) and
an object has a visible_size (0 for objects 1/2 footprint for multis)
* use in_range instead of pol_distance
* corrected order of checks
* fixed warnings
* fixed visual size of multis
testclient added wornitems pkt support
added tests for los
* corechanges
* replaced baseclass x,y,z,realm members with Pos4d.
Adapted the code, no changes except making the compiler happy
* review changes
* Fixed gotten_item
* fixed copy&waste
Authors are not forced to use the clang-format setting, but should
atleast be inspired by the style.
The only thing which is now not allowed are tabs for ident/alignment!
Currently plib/systemstate, pol/uvars, pol/ucfg, pol/multi/multidef
Next step should be to split them based on usage, since its currently a bit of include hell...
Created a new file (msghandl.cpp) and moved the code from pol.cpp there.
Moved related files to the "network" folder, where they belong. Fixed
include names... (we should make this relative to the project root!)
