Use cvs2svn-2.4.0 from mg13's space.

Use cvs2git.options file instead of command line args.
reimport.sh: match paths to cvs2git-funcs.
reimport.sh: change naming for ensembl core.
Move previous ensembl.known-good.txt out of the way.
New ensembl.known-good.txt

Optionally kill off specified branches.
ensembl.known-good.txt: branch-ensemblgenomes-17-70.
