templater: indicate if branch needs to be pushed to a remote It's useful to know when you've modified a branch that exists on a remote. A typical case is when you have pushed a branch to a remote and then rewritten it. This commit adds an indication in the `branches` template keyword. A branch that needs to be pushed to a remote now has a `*` at the end (similar to how conflicted branches have a `?` at the end). Note that the indication only considers remotes where the branch currently exists, so there won't be an indication that the branch has not been pushed to a remote. Closes #254

templater: add wrapper that turns template back to string property I have no idea whether or not any template expressions are intentionally allowed as a label, but it makes sense to write something like 'label("phase-" phase, ...)' (if we had a phase keyword.) So I decided to add .into_plain_text() instead of stricter .try_into_string().
