modifies the hollow metrics API; that'll probably be implemented soon
adds init stages
changes SSatoms to not abuse its `initialized` variable
closes#6858
refactors the asset subsystem to make it much more managed
adds support for 'deferred' assets for tgui, which will be later used
for things like tgui character setup and admin panels.
deferred means that it'll be 'sent in a timely manner after the ui
opens', as opposed to 'sent before the ui opens'
