hgweb: make different kinds of commits look differently on /graph Regular hg log -G uses different symbols for some graph nodes, such as commits that close branches and hidden commits. It also marks the currently checked out commit with "@". Since hg serve is sometimes used/recommended as a more visual alternative to CLI, it makes sense to port these features to hgweb. "graphnode" includes the style of a particular node and also if it's currently checked out or not, both at the same time. This is different from hg log -G (which uses templatekw.showgraphnode), where there's only place for one character, but hgweb doesn't have this limitation, since it uses <canvas> and not plain text. I'm using one string of 1 or 2 characters in this patch, it's not the most self-explanatory format, but it's concise, uses the same characters as hg log -G, and is internal to hgweb (i.e. not used for json-graph). I'm more or less fine with how things look visually, but there's still room for improvement. Feel free to criticise or point me to good-looking graphs of this kind for inspiration.
