This sets up room for the '__equal' metamethod to be added
- cosmoO_equals now requires the state to be passed
- cosmoV_equals now requires the state to be passed
- cosmoT_get now requires the state to be passed
also changed print() to print raw primitives instead of generating a <string> needlessly. helped performance immensely in scripts like `examples/increment.cosmo`
Optimized the NaN box to be byte aligned, performance under the fibtest.lua script improved by ~2.5 seconds (~31 before ~28.5 after on cpunch's machine)
also cleaned up some misc. comments
