[CogManager] Correctly separate core, install and other cog paths (#1983)

Browse Source 
* [CogManager] Correctly manage core and install paths

This keeps the core and install paths separate from those set in the
config.

It also displays the core path separately in `[p]paths`

Resolves #1982.

* [CogManager] Fix old reference to method removed in previous commit

Also did a bit of a general cleanup of cog_manager.py's code

* Make the core path a class attribute

* [CogManager] Paths should default to a list
