Add option to show cache dir

[NeoTheThird]

It'd be nice to have an option to show the cache directory in the menu. Electron shell has a feature for that, which could be called on the utils.getUbuntuTouchDir() function.

Device cache or Installer cache? And what would be the use case for it?

The installer uses a cache directory on the computer where the logs, settings, and downloaded files are stored. The location varies depending on the OS and package. The use case would be maintenance, eg. looking through the downloaded files. A convenience feature, mostly. Especially with the snap package, the location is not easy to find for the uninitiated.
