Add basic enemy attack + flash white (color is customizable) when attacking
Added flashing animations when enemy or player takes damage
Added "Radius" property to skills
Fixed the display of floating point numbers to display only 1 decimal digit
Changed the scale of player health / mana (x10) to be able to show variations without having to use decimal point numbers
Reworked the way "number of uses" was handled to fix: NumberOfUses carries over each iteration
Fixed bug where parent selection changed the order of the skills for the player in the next level
* Solution is a bit cumbersome, as it involves making the saved data immutable (making it a property), thus making it unavaiable in the inspector for tweaking.

Renamed some prefabs to have names that are easier to handle
* Wave generation now use a Settings class to easily switch between Dev and Prod
* Added a slight random to enemy firing time
Now clicking directly on a skill will display the skill attributes
Reworked the end-level screen (factored skills, used the SkillDetails to display info)
Fixed a couple of bugs caused by previous commit, where the skill wouldn't fire properly anymore
