[COGITO PATCH] Heads and tags in subdirectories

[COGITO PATCH] Heads and tags in subdirectories

[Santi Béjar]

Keep heads and tags in their respective subtirectoris named as
the branch. This fixes the case where two repositoris have tags
with the same name.

Add a "-a" flag to cg-pull to download all the repositories heads,
so you can now do a "cg-log -r repo#branch" (cg-Xnormid repo#branch
job).

The transition is automatic when you do the first "cg-pull repo".

[COGITO PATCH] fetch_local -d behaves different from other fetch_*

[Santi Béjar]

"fetch_local -d src dst" does not respect the dst directory name 
if both have different names. So

fetch_local -d /path/to/some/src /path/to/dst

copies to /path/to/src.

In fact this way it's never used in the current cogito so it's not
really affected but it's needed in the case where the heads and tags
are in directories.

Teach cg-init about the origin directory.
