Fix items hard-coded to go to Data/

[Vlek]

There are a bunch of places that are hard-coding the search for items within the Data/ folder. These all need to be changed to a configurable location.

In looking at Channel.cs, there appears to be a General.SavePath that I might be able to set and use.

This is a would-be-nice.

What I have done so far is to at least have the items generated in the release correctly so that it will be added in a way that this will work.

However, the end goal would be to have this all bundled into the .exe. If someone wants to change the code, the way to do this is via a version controlled repo change and a new release generated and a docker container spun up.
