EasyDMG Files

The main feature of this update: you can now choose a location for EasyDMG to install to, rather than only the Applications folder, along with a new default location for users on non-admin Macs who don't have access to /Applications.

• Added a new Install Location setting with Applications, Personal, and custom folder choices.
• Made EasyDMG useful on standard, work, school, and shared Mac accounts by offering the personal Applications folder when the /Applications isn’t writable, as well as a custom folder option.
• Added clearer recovery choices when an install folder is missing or unavailable, so you can adjust Settings or take over the install manually.
• Protected apps with system extensions by guiding them to the system Applications folder, where macOS requires them to live, instead of completing an install that would not work.
• Kept existing users' install behavior unchanged while choosing a writable default for people setting up EasyDMG for the first time.
• Improved Settings and install-dialog behavior, refreshed the wizard hamster artwork, and added a silly South Park reference to the About tab. Gotta keep it fun :)
