Asset Packs: Optimize icon loader (#164)

* Original pointer can be const

* Back to const icons

* Missed this one

* Simpler string alloc

* Single allocation and header struct for static icons

* Shared allocation and meta struct for animated icons

* Only try to load if dir exists

* Restructure momentum lib

* Use some internal headers

* Swap icons at draw

* Properly init and free, no more original in icon struct
