This pull requests add support for hiking tracks. Tracks are displayed as wide dashed lines with osmc symbols along the track.
Data are taken relations with osmc symbols. As renederer I used Touring-view_(more-contrast-and-details).

It is need to merge also mhamrle / Osmand,  mhamrle / OsmAnd-tools, mhamrle / OsmAnd-core
