Added enemy health bar

First, I want to mention that unity deleted some assets from
L_FG_Asstets_Pack_Lite. I'm not sure why. Sorry about that.. add them
back if it's an issue.
2 bugs:
1- if you kill one enemy, you can't see the health of the other enemy
2- if you kill one enemy before having ever damaged the other enemy, you
can't attack him anymore
readed missing assets files

not all were missing

pressed
Added Unit tests for GameOver Screen
Added Character Stats

Press s to see the character's stats but an issue is still present since
the box is drawn several time. It's an issue likely related to frames

Added Unit test for fighting/damaging an enemy.

Reference: US 1.4: Be able to fight monsters
ADD: server-client connection. (NB server code currently must be hosted in a different project in order to be able to run two unity projects on same machine — later we can have some code to determine if any random player wants to act as the server).
ADD: basic chat between server and client.
