Enabled the RTSCamera, need to be tweaked.
Rotation when moving enabled, computed to 6 different direction.
CardRenderSystem and EntityRenderSystem both use the RenderComponent.
Card can now be played on the field to summon unit.
WIP version, stable.
Added two new element "SHOCK" and "NULL".
"NULL" is the element returned by default now, this correspond to nothing (inexisting hex got this properties) "this will be mainly an error element for the time being"
Added method in main to getKeyByValue (reverse hashmap)
Tonegod issue with no header showing, half solved by adding a param.
Animation system implemented/improved.
Hextile contain a field saying if walkable or not.
RenderSystem implement tilelisteners, update are done properly when a tile change with units on it.
Added comment, moved/renamed some class.
Removed some deprecated file.
Issue : Old saved map does not longuer fit new parameter, this lead to weird loaded map.
Extend of DefaultEntityData to make a bridge between the entity syetem and the hexsystem.
Collision summon corrected, unit does not stack on same place,
When unit move, the moving unit got the priority over sommoning,

Added javadoc, corrected commend, corrected import.
