Add conditions for applying customization

[XomaHost]

Customize keeps adjustment when executing emotes, so when making adjustments to idle face expression and then using emote with expression, it makes the expression go "stronger". The example with lips shape and /smile is on the picture:

Adding conditions to enable/disable customization if certain requirements are met (for example execution of an emote, equipped a specific items) can extend functionality and create more applicability.

This isn't something that I plan on implementing. Will keep this open for unlikely case of someone else willing to implement this.
