New extension: Signals

[github-actions]

Description

Adds an Call Signal action and a On Signal Call condition, allows for re-use of actions from different conditions without rewriting the same actions repeatedly.

How to use the extension

Use Call Signal as an action, and then use On Signal Call as a condition, using SignalName as the linking parameter.
This call can be re-used as many times as you want, it will go through the list of actions on the sheet once whenever called.
Works with sub-events, Call Signal can be put before On Signal Call and vice versa.

Test file contains 3 buttons, all of which toggle the visibility of a sprite, using a Call Signal and an On Signal Call action.
