Subject: [PATCH] hg-fast-export: support new --hgtags option

Add support for a new --hgtags option.  When given, any .hgtags
files that may be present are exported.

Normally this is not desirable.  However, when attempting to mimic
the actions of other hg exporters that always export any .hgtags
files this option can help produce matching export data.
