conandeps: colour tree tags in HTML and text

Browse source 
The tree builder now emits typed tags (path, override, missing, ...) and
both renderers colour by kind: <span class> in the HTML <pre> block, ANSI
in the terminal (path dim, override yellow, missing red). Previously the
HTML tree was one escaped string and only MISSING was coloured in text.
