Full install does not need history and branch

[MauroMombelli]

On the "full install guide" please change git clone https://github.com/andrewd18/df-lnp-installer.git with git clone -b master --depth 1 https://github.com/andrewd18/df-lnp-installer.git so user will not download history and uneeded banch.

plaese do the same even for all git clone inside the script, download time and dick usage will be a lot smaller
