Ubuntu14.04/v1.1

@mr-c 
Is over here better?
I'll go ahead and make the pip install change.
As part of the move to v1.1 we need to change the file extension from ".kh" to ".pt" or ".ct" as appropriate
Counting tables such as produced by load-into-counting should have the extension ".ct"

When you're done the string ".kh" shouldn't appear in the Makefile anymore
