v7.0.0-RC1

This is a major version update from v6.x, and it brings several changes. Keep in mind, this version is not recommended for slower platforms, you should prefer Amiberry-Lite for those (which will also get an update, after this one is finalized). Some of the most important changes in v7 are:

• Amiberry is now delivered as a package, instead of just an archive with binaries. This also means that you don't have to manually install the dependencies, before you can run it (the package will take care of that for you automatically). For Debian or Ubuntu based systems there's a .DEB package, for Fedora there's RPM and for macOS users, there are DMG images that can be used. You can now install Amiberry by downloading the archive, extracting it, and doing something like sudo apt install ./amiberry-XYZ.deb (for DEB). Upgrading to a newer version becomes as simple as installing it on top again. Uninstalling it is simple as well (sudo apt remove amiberry) and it will clean up the dependencies after it. Check the main README for instructions per platform.
• The directory structure handling has changed. Amiberry will now install itself into standard locations, placing shared libraries where they are expected in the system, and will use the user's HOME folder to create an Amiberry directory, if it doesn't exist. That will contain the user-configurable stuff, like directories for Floppy images, Harddrives, Configurations etc. Meanwhile, internal directories are placed elsewhere, to reduce clutter. Check the Wiki for more details: https://github.com/BlitterStudio/amiberry/wiki/Amiberry-directories
• The MacOS binaries are finally signed with an Apple-recognized developer certificate, and they are notarized. This means you no longer have to manually bypass the system's security, to allow it to run. You can just drag and drop it to your Applications and start it up like any other downloaded App. You'll only get a warning that this was downloaded from the Internet, as expected.
• Hi-DPI support has been added, so if you're running this on Linux with scaling enabled, or macOS Retina displays, things should look better now.
• Integer scaling has been added and improved. Check the wiki for more details on this as well.
• Serial port support has been fixed, as it was broken for some versions now.
• GUI Themes have been implemented, so you can now customize the color scheme.
• The whole list of Expansions from WinUAE have been implemented, including PPC, PCI, DSP, custom graphics cards, network cards, SCSI controllers, etc. The Expansion panel was refactored significantly, but the functionality is trying to match the same one from WinUAE, to make things easier between the two emulators.

🎉 New Features

• Implemented the full functionality of the Expansions GUI panel
• Implemented SLIRP support
• implemented SERIAL_ENET functionality
• added Shared serial option

• Added PCEM support from WinUAE, with fixes for ARM/ARM64 added on top
• Added PCI support from WinUAE
• Added MAME (a2410 and TM34010) from WinUAE
• Added QEMU (various gfx cards, network cards, SCSI, etc) from WinUAE
• Added DSP emulation (disabled for now)
• Added SANA2 support (not visible in the GUI yet)
• Merged the latest updates from WinUAE 5.3.1
• The directory structure used is now changed, to be more standardized. User-configurable folders are now created on startup under the User's HOME folder. Shared libraries will be placed in the expected location based on the system used. The old directory structure included in the repository is cleaned up, as empty directories are no longer needed.
• Implemented GUI Themes. You can now customize the colors of the GUI, and save those in separate theme files.
