Support substitutions for repository/branch names.

This patch adds support for 's///' style substitutions for the
repository/branch names in the match rulesets. Useful when e.g. eliminating
characters not supported in git branch names.

Syntax:

match /...
    repository some_repo
    substitute repository s/pattern/replacement/
    branch some_branch
    substitute branch s/pattern/replacement/
end match
