Move ICP properties into settings directory

As a developer I would like all of the settings that make an instrument unique to be in one place under version control. The `isisicp.prtoperties` file contains settings for the icp, such as whether it's in simulation mode, but is currently fixed to be located relative to the ISISICP binary. It should instead be in the `Settings` directory. This will require changing the path that the ICP looks in.

## Acceptance Criteria
* ICP configuration files are stored inside the C:\Instrument\Settings\config\NDXaaaa directory
* Add system test to ISISDAE
* It needs to be done by Dom and Freddie
