Might Fix Resource Lag

Removes the dynamic setting of preload_rsc, because BYOND does not appear to respect it if it's not compiled in, and the dynamic nature of it is unused to my knowledge. If you need to change it, you can change a define in _compile_options.dm
This should now properly set it to '1', which should load all the resources at once, which might make some significant slowdown when first connecting, but should be preferable to constantly getting mini-lags when moving to new areas or hearing new sounds (like when getting shot at!).
