I added the option to choose the Vivado file type manually (in case Vivado detects it wrongly).
Additionally the scrtipts use "VHDL 2008" file type for all *.vhd and *.vhdl files. Vivado uses VHDL 2002 by default which is quite restrictive. VHDL 2008 does not have any drawbacks, so we can use it as default.
