Amusifier fails #1164
Description
Using Amusifier outside of a Git environment from which version identifiers can be picked up results in an error:
Traceback (most recent call last):

ValueError: unexpected '{' in field name
This is caused by **variables not containing the necessary variables to construct a version:
distance = "{{next_version}}.dev{{distance}}+{{vcs}}{{rev}}"
dirty = "{{base_version}}+d{{build_date:%Y%m%d}}"
distance-dirty = "{{next_version}}.dev{{distance}}+{{vcs}}{{rev}}.d{{build_date:%Y%m%d}}"
This error is primarily not very clear, maybe it would be best to let amusifier fail early if used outside of a Git environment?
