Updates/fixes to memory settings

- Update memory states to be Good performance, Ok performance, etc.
 - Update header info to be based on history rather than
   instantaneous
 - Color memory bar differently based on state
 - Fix run frequency bucketing to be correct
 - Show dialog for selecting duration, and fix duration selection
 - Update process naming to:
      - If process name is "anything:xxxx" then show "Xxxx"
      - If process name is "com.app.package.interface" then show "Interface"
      - If process name is the package name then show the app name
      - Otherwise fallback to the process name string
