git-svn: Add per-svn-remote ignore-paths config
The --ignore-paths option to fetch is very useful for working on a subset
of a SVN repository. For proper operation, every command that causes a
fetch (explicit or implied) must include a matching --ignore-paths option.
This patch adds a persistent svn-remote.$repo_id.ignore-paths config by
promoting Fetcher::is_path_ignored to a member function and initializing
$self->{ignore_regex} in Fetcher::new. Command line --ignore-paths is
still recognized and acts in addition to the config value.
