color: add effect to the template symbol table

Previously, words like 'red' had to be protected by quotes before passing to
the label template function. Now, we add color effects to the symbol table so
that commands like,

$ hg log -r . -T "{label(red, node|short)}\n"

can work without the need for quoting.
