templater: expand list of parsed templates to template node

This patch eliminates a nested data structure other than the parsed tree.

  ('template', [(op, data), ..]) -> ('template', (op, data), ..)

New expanded tree can be processed by common parser functions. This change
will help implementing template aliases.

Because a (template ..) node should have at least one child node, an empty
template (template []) is mapped to (string ''). Also a trivial string
(template [(string ..)]) node is unwrapped to (string ..) at parsing phase,
instead of compiling phase.
