remote: fetch, correct behavior on tags

[mcuadros]

This fix #371 and #407

This PR remove the all behavior or fetching all the tags from a remote when a wildcard is being use, to the correct one.

It implements two different options TagFollowing, this means that fetch the tags from objects being fetch (or fetched) making usage of the include-tag capability, or the option AllTags downloading all the available tags.

[smola]

You might want to exclude include-tag capability when the AllTags options is used? Although it seems that git unconditionally enables it whenever it's supported.

[mcuadros]

Yep, is kind of useless, and git is not using it when --tags is used.
