Bug 19821: Install sample data, ES mappings and Version syspref

Also move .proverc to .proverc.dist, so it cannot be used by accident.

Different ways to use it:

1/ prove --rc .proverc.dist
   Use defaults

2/ cp .proverc.dist .proverc && prove
   Allows to configure db name, marcflavour, and prove options
