set version/projectname properly

lbmk used to set version/versiondate directly in
err.sh, but now it's handled there by a function,
which is called by the main script.

script/update/release hadn't yet been adapted. the
only change necessary is to call check_project()

script/update/trees also makes use of it

script/build/roms is using "projectname"
