Allow ignoring part of history when calculating version #538
Description
Based on discussions from #470 we reached a consensus that you should be able to ignore before a time period. This can be a configuration value:
ignore-commits-before: 2015/01/01
This allows when repositories have bad commit messages or something else which is causing a high version number (see #443).
ignore-shas:
sha1
sha2
could be another option, the logs tell you what commits different versions are coming from, so it would be copied straight out of the logs to ignore that particular commit. Having both would not be bad.
