[WELCOME] Minor usage improvements. 
- Don't hardcode the installer file name in ExpandInstallerPath() but
  provide it from a parameter. Return TRUE/FALSE if the installer file
  is/is not found.

- Expand any environment string present in the items command line.

- Enable/disable the menu buttons depending on whether or not an
  associated command is present.

- Enable mirroring from resources.
