template: add ifcontains template function

Adds a template function with the signature 'ifcontains(item, set, then[,
else])'.  It can be used to do things like '{ifcontains('.hgignore',
file_mods, label(...), ...)}' to color commits that edit the .hgignore file.
A future patch will add the revset() function which will combine with
ifcontains to allow us to color commits if they are in the revset.
