 - Adds support for system-wide configurations.  This improves support for package maintainers.
 - Help function to print key bindings
+- Help prints locations of config files (color schemes & layouts)
+- Help prints location of logs

+- Extensions are now built with a build tool; this is an interim solution until issues with the Go plugin API are resolved.
 
 ### Removed
