Assortment of fixes - particularly for reading saved cctree.out

[qais-yousef]

I started with not being able to use the saved cctree.out as in #16 and ended up with a bit extra fixes on top. Which I'm not sure how good they are - particularly the one about sorting. taglist() fails to find lots of elements and I literally hacked it to reduce the error rate, but not entirely eleminated it.

It seems this project is no longer maintained - but hey in case anyone finds this useful..
