update: add `-R, --recursive` flag

[casperdcl]

dvc update -R/--recursive should recursively find & update all DVC-files which are updateable (and be incompatible with --rev).

Allows replacing:

dvc update <long list of files> && dvc repro -P

with:

dvc update -R && dvc repro -P

Let's not take -a, as we use it for --all-branches in othe rplaces already. Let's just use --all for now.

[skshetry]

It'd be symmetrical with push/pull/add if we used --recursive/-R instead.

I'd like to implement it. May I?
