Add investigate.vim
CtrlP no longer jumps you to the file if it's already open.

This makes it easier to maintain multiple Tab workspaces involving the
same files. For example, in one workspace you want a class and its spec,
and in another tab you want to see that class in context with another
collaborator. This allows you to open the window multiple times.
