[Feature] `TransitionKey` is not being parsed or handled between `ConditionState`.

[ViTeXFTW]

Problem

When creating objects which use special transitions between ConditionStates, a TransitionKey is defined which a TransitionState block can use to now what animation should play when going from one state to another. Currently this is not being tracked in the server and the TransitionKey is not being checked in the following blocks.

Proposal

The server should parse the TransitionKeys and make sure that they:

1. Are used in the draw module.
2. That if a TransitionState uses a TransitionKey that the key exists.
