Branding: Consider changing name from "Crystal Web Archiver" to "Crystal"

[davidfstr]

The former name "Crystal Web Archiver" is a real mouthful. And it's not entirely clear what a "web archiver" is. A "website downloader" would make more sense.

Changed:

• [x] README title
  • "Crystal Web Archiver" -> "Crystal: A Website Downloader"
• [ ] The "APP_NAME" and "_APP_NAME" constants in the source code, which control all of the following items:
  • [ ] Binary name on macOS and Windows:
    • "Crystal Web Archiver" -> "Crystal"
    • On Mac OS, this affects both:
      • APP.app
      • APP.app/Contents/MacOS/APP
  • [ ] Title of application menu on macOS
  • [ ] Title of application menuitems on macOS
    • "{Hide,Quit} Crystal Web Archiver" -> "{Hide,Quit} Crystal"
  • [ ] Location of log files on macOS and Windows
• [x] Project title at dafoster.net: "Crystal Web Archiver" -> "Crystal: A Website Downloader"
  • Appears in Twitter/X posts:

Unchanged:

• Git repository name: Crystal-Web-Archiver
  • No strong need to rename at this time.
• Linux binary name: crystal
• PyPI package name: crystal-web
