Archimage 4.2 (#32)

* Add new template on steroids, named "NEW-junest.sh"

- unuque flexible AppRun that allows to run the AppImage using Namespaces via Bwrap and switches to PROOT in case the system has Namespaces restrictions (see Ubuntu)
- always made an updatable AppImage
- multilib in now optional, you can enable it via CLI
- if the app is on AUR, the cli will suggest to enable ChaoticAUR
- the standard configuration only enables network and audio keywords, and in most case it is enough for the app
- extract dependendes of dependences and dependences of the latter
- include better support to open external browsers (tested with Firefox)
- add an exclude list not to include developer packages (gcc, make...)
- include optdepend as dependences
- download and extract optdepend packages before the others, not to include their dependencies
- move pk and p11 internet keywords from the CLI to the script
- changed the question for network support
- add message of each process when detecting libraries
- improve speed of libraries detection for dependencies
- add "extract_count" variable to set dependencies extraction level (default 1)
- include more coreutils binaries
- use worldwide mirror for Arch Linux in case the script is running on github actions
- more elegant way to remove bloatwares
- set extraction level on dependencies
