fix(vcs): refine log ref labels, row height and favorite star (#335)

Git Log ref labels use an outlined tag glyph in the ref colour instead of a solid flag; log rows are 26px with wider graph lanes and larger nodes. With Highlight › Current Branch on, commits outside HEAD are dimmed instead of the current branch being tinted. Excluded folders in the project tree get a tinted row background (Tree gains an optional rowClassName). The favorite star is a rounder shape, and the filled one has no separate outline stroke.
