Polylines deported from resource pack to the ruleset

Features:
- polylines attached to countries as border list-list-points(in DEG, not RAD)
- each country may precise it's full border
- the country rule memorize polylines transcoded in RAD
- after full ruleset loading and processing, a polyline optimization eliminates the duplicate border segments in order to optimize globe drawing (preserve the existing state)
- allows to add new countries/delete countries (see also PR 699 and 701) along with their borders by ruleset only.
