why:
it was convenient to have relocatable source modules when writing the
vm interface wrappers. this patch moves it back to the standard.
also:
there are no deep links into the vm folder anymore which leaves some
room for manoeuvring inside
why:
relative paths make sources inherently non-relocatable
details:
import base is set to the nimbus directoy, so importing ./stack
from file interpreter.nim becomes vm/stack etc.
caveat:
a file named nimbus/strformat.nim would clash with strformat (but
not with std/strformat)
