Serious bug in npc.inner

I found a serious bug in npc.inner.
This bug could result in wrong expecation values and Lanczos/DMRG giving completely wrong results.

Luckily, the bug was only on the github master branch for two weeks (since March 02), so I hope it didn't cause too many problems yet.

In case you did a "git pull" in the last two weeks, please update to the newest version.

Further details in github issue #22.
