importproject

Already did a post for it ( #991 ), but I can't seem to re-open the issue. In any case I still believe this would be a great addition. I've done a stab at it at here, it works but some tests doesn't pass, my understanding of lua isn't good enough for me to easily be able to fix it sadly. Currently it's only tested on MSVC ( needed to change one line in sln2005.projects() to make sure it computes the correct path ). There's a small example here that roughly shows how we use it. I understand this take on it won't make it into the master branch, but might be interesting for others to have a look at.

Start by reviewing issue #991 and the linked premake-core attempt, especially tests/test_importproject.lua and the sln2005.projects() change described in the issue. Check which tests currently fail and whether the proposed importproject behavior is still wanted; done would require an agreed implementation that passes the relevant tests beyond the reported MSVC-only case.
