Support for Multiple Animations (modelrender)

[Jsynk]

Added a function in modelrender to support multiple animations it´s kinda like setAnimation+setAnimationTime(optional) used multiple times for each animation with the exception that it uses updatePose immediately and is able to pass a ignoreBoneNameFilter(RegExp) to the updatePose function so the animations can ignore to update certain bones and in that way you can use

let animations = [];
animations.push({ name:'run', time: this.ani['run'].cur_time });
animations.push({ name:'aimGunZ', time: aimAngleZ, ignoreBoneNameFilter: /legs|hips/g });
this.actor.modelRenderer.setMultipleAnimations(animations);

animation 1 would set the run pose on all bones
animation 2 would set aim gun pose for all bones except those who has legs or hips in their name

this is my first week programming with typescript and with the superpower-game source code
hopefully it isn´t to bad.
