templater: load and expand aliases by template engine (API) (issue4842)
Now template aliases are fully supported in log and formatter templates.
As I said before, aliases are not expanded in map files. This avoids possible
corruption of our stock styles and web templates. This behavior is undocumented
since no map file nor [templates] section are documented at all. Later on,
we might want to add [aliases] section to map files if it appears to be useful.
