System specific update

Reload-Scripts now loads Platform/OS specific scripts depending on
current state.
This required the SystemName class

sranger is an example of running ranger as sudo, but only in Linux.

Moved Get-MyAliases into Reload-MyScripts, and changed Reload-MyScripts
to load Aliases dynamically via the Aliases directory.
