In particular, this changes the order so that the instance gets created
before downloading the mods (like other install tasks), and the mod download
directly puts the files in the staging folder (like the others), instead
of that weird makeCached and copy stuff.
This fixes some issues with modpack downloads from FTB, like creating an
instance with no mods in it.

While working on pack updating, instance naming always gets in the way,
since we need both way of respecting the user's name choice, and a
standarized way of getting the original pack name / version.
This tries to circunvent such problems by abstracting away the naming
schema into it's own struct, holding both the original name / version,
and the user-defined name, so that everyone can be happy and world peace
can be achieved! (at least that's what i'd hope :c).
