configuration: Redo serialization

[Ondraceq]

• Add two phase serialization - to a tree structure (in c++) and in second step to json
• Change module representation

New representation:

RofiWorld = { modules :: List<Module>, moduleJoints :: List<ModuleJoint>, spaceJoints :: List<SpaceJoint> }

Module = GenericModule | UniversalModule | PadModule | ... // { type :: string, id :: int, attributes :: Any?, ... }
GenericModule = { type :: "generic", id :: int, attributes :: Any?,
        connectors.count :: int, shoes.count :: int, bodies.count :: int,
        joints :: List<ComponentJoint> }
UniversalModule = { type :: "universal", id :: int, attributes :: Any?,
        ( alpha :: int, beta :: int, gamma :: int | joints.positions :: Array<Array<int, 1>, 3> ), joints.attributes :: Array<Any, 3>?,
        connectors.attributes :: Array<Any, 6>?, shoes.attributes :: Array<Any, 2>?, bodies.attributes :: Array<Any, 2>? }
PadModule = { type :: "pad", id :: int, width :: int, height :: int, attributes :: Any?,
        connectors.attributes :: Array<Any, 6>? }

ComponentJoint = { joint :: Joint, from :: ModuleComponent, to :: ModuleComponent }
SpaceJoint = { point :: Array<int, 3>, to :: Component, joint :: Joint }
ModuleJoint = { from :: Connector, to :: Connector, orientation :: Orientation }
Joint = RigidJoint | RotationJoint | ... // { type :: string, positions :: JointPositions, ... }
RigidJoint = { type :: "rigid", positions :: Array<int, 0>?, transformation :: Matrix? }
RotationJoint = { type :: "rotation", positions :: (Array<int, 1> | int), ... } // Specific, but I don't know

// Component in the current module
ModuleComponent = ModuleConnector | ModuleShoe | ModuleBody
ModuleConnector = { connector :: ConnectorId }
ModuleShoe = { shoe :: ShoeId }
ModuleBody = { body :: BodyId }
// Component with id of module it belongs to
Component = Connector | Shoe | Body
Connector = { id :: int, connector :: ConnectorId }
Shoe = { id :: int, shoe :: ShoeId }
Body = { id :: int, body :: BodyId }
// Component identifiers
ConnectorId = int | <module specific>
ShoeId = int | <module specific>
BodyId = int | <module specific>

Orientation = "North" | "East" | "South" | "West"
Matrix = Array<Array<int, 4>, 4> | "identity"

[Ondraceq]

Also the callback should get all elems on path (e.g.) RofiWorld Module Connector index (all const).

And everything should be already built - this means that attributes are processed after parsing the configuration.

As discussed at #279
At least code parsing json should be separated to functions, but better solution would be to do the refactoring
