Conty now uses statically linked bash and busybox, so it no longer depends on system-wide bash, tar and gzip. And other improvements in this commit: * NVIDIA_HANDLER improved and enabled by default. * Reworked the self-update feature, it uses fuse-overlayfs now instead of extracting the whole image. * Added the CUSTOM_MNT, which allows to use Conty with already mounted custom moint points and directory structures. * create-conty.sh now automatically sets the correct sizes in conty-start.sh * Added more locales
