Added support for getting the player's current building mode (build, color, config, blueprint)
Added support for getting the current game's mode (building, playing, prefab etc.)

Fixed getting the selected blueprint
Fixed block groups not being assigned to first block

Added a way to store block groups as blueprints
Blocks can be added/removed from block groups, although it doesn't work well atm
Added some patches to the test class in an attempt to debug an unrelated issue
Added a command to test placing a block group
Added a SelectedBlueprint property to the Player class

Removed BlockIdentifiers.OWNED_BLOCKS as the original got replaced with an array
Added the correct group for each supported functional block
Removed EntityFactory property from IEntitySerializer as it is provided on deserialization

Fixed setting player properties
Changed player rotation to float3
Added constructor for BlockColor with an index param
Improved Player.Exists() ~~hopefully~~

A bit hacky, but it works

Placement, movement, rotation, removal
Block looked at (in Player class), connected blocks
