rework all code using tags

Add three utility functions:

tags(): get (and possibly load) the tags mapping
tagslist(): sort tag,node by revision (aka topologically)
nodetags(): return a list of tags associated with a node (also cached)

Update all the code using tags to use these.

Simplify identify code
 make unknown always visible if printed
 don't ignore tip pseudo-tag
