Refactor alt handling

* Simplify score_file() by using case in instead of nested ifs with regexps.
* Merge record_score() and record_template().
* Alt condition processing no longer stops when a template condition is seen
  but continues processing to verify that all conditions are valid (as the
  documentation says it should). Fixes #478.
* Support alt dirs with deeply nested tracked files (fixes #490).
* Use git ls-files to filter out which tracked files to consider for alt
  processing. Should speed up auto-alt (#505).
* Use nocasematch when comparing distro and distro_family. Fixed #455.
