Javelins reworked
-Added stone and metal javelins.
-Added stone and metal javelin heads.
-Added javelin head molds.
-Javelin are crafted with a stick and a javelin head above it.
-The melee damage is 62.5% and the range damage 80% of the DamageVsEntity defined by the material. So the javelin should not make the sword and mace obsolete.
-The pattern for knipping and the plan of the javelin heads is (dot means empty/removed field):
XXX..
XXXX.
XXXXX
.XXX.
..X..
-The english and german translation is complete. The french, spanish, itilian and russian translation contain only the new javelins and javelin head based on Goggle translater and the existing language snippets.
Added Textures
-Textures based on existing TFC textures.
-Texture of EntityTerraJavelin is still the original texture for all javelins.
