Allow to use parameters and properties in the variable action and condition

[D8H]

Changes

• Properties and parameters can be used in the primitive variable conditions
• Properties can be used in the primitive variable action
• Change the priority to:
  • Global variables
  • Scene variables
  • Properties
  • Parameters
  • Local variables

Technical solution

• Properties and parameters are used to generate the VariablesContainersList.
  • It allows to finely choose the priority.
  • It's consistent to what is already done for the ObjectsContainerList.
• Variable instructions uses 2 new parameter types variableOrPropertyOrParameter and variableOrProperty.
  • Instructions that use variables are references still use the parameter type variable.

TODO

• Add tests
• Try to find regressions
