Script: Improves the rootflags option in the kernel command line: - Remove "rw" flag. - Parse fstab mountoptions and add them to rootflags: Adds functionality to read in snapshot specific mount flags from the respective fstab and uses them in combination with the new config option, while the latter is prioritized. Both places can, but don't need to define mount flags. If either of them doesn't, it will simply not be taken into account. Config file: Adds a new config variable "GRUB_BTRFS_ROOTFLAGS": - The new variable is used to include user-defined rootflags in the kernel command line of generated snapshot bootmenu entries. See config file for more infos.
