Refactor InRangeUnobstructed and add extension methods (#1925)

* Sort out InRangeUnobstructed and add extension methods

* Rename client RangeChecks to RangeExtensions

* Add container extension methods and test

* Add missing component methods

Component to container
Grid coordinates to container
Map coordinates to container
Local player to container

* Actually use the field

* Merge fixes

* Add popup argument to local player extension methods

* Reduce code repetition for client range extensions
