Modified portugal.poly

Hello, I followed the instructions from:
http://code.google.com/p/osmand/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Priority%20Summary%20Opened%20Modified%20Milestone&groupby=&sort=&id=1760

Copied portugal.poly, converted it with osm2poly.pl, modified it in JOSM, and converted it back to poly with osm2poly.pl

Added Açores islands, and corrected/modified Portugal to include river borders margins.
