angelescuo ghostbsd-build

[angelescuo]

Hello

I have added in agelescuo to ghostbsd-build some features:
1) can install freebsd in chroot using sources or tarballs (fetched from freebsd)
2) if using sources built kernel and userland can be used by any flavour if buildkernel and buildworld is not set
3) there is also a freebsd_update routine if freebsd is installed in chroot using tarballs but now is deactivated due to freebsd-update bug. If not using freebsd_update routine we have only the RELEASE defined in ghostbsd.defaults.conf
4) We can define even FreeBSD RELEASE to be used in chroot if using tarrballs.
5) each flavour put the iso in separate dir under desired ARCH
6) each flavour push the logs in different dir under desired ARCH
7) all dirs from / are mounted using mount_unionfs so those dirs are rw even in iso
8) portsbuild and portsinstall routines are comasated in one file now called gbsdports.sh under scripts subdir
9) Improved cleandir for every flavour under clscripts as an example clean_mate_i386 ...
10) because of points 5 and 6 can be launched multiple builds for different flavours arch in parallel ( if computer is enough powerfull)

Thank you
