Fix Cog resolving string properties and erroneously including quotes

[moolicc]

Currently, on startup Cog runs over the AppSettings and attempts to load settings into the static member. However, not 100% sure if this is a Cog issue or a setup issue on the Wallop side.

Investigate and move the issue to Cog if necessary.
