[PATCH 2/2] [D] Remove search_parents parameter from d_lookup_symbol_imports

[Iain Buclaw <ibuclaw at gdcproject dot org>]

Whilst looking at part one, a moment of insight came to me and I
realized this code is completely nonsensical.

For a start, when importing modules, you don't gain access to all
parent packages of the given module.

To add some confusion, even the comment was wrong.  It doesn't even
cater for the example given (it's d_lookup_symbol_module that walks up
each block scope).

I feel embarrassed it didn't come to me before. :-)

Regards,
Iain.
