Allow the character `/' in tag values.

[tsuna]

There's not reason why / cannot be allowed in tag values, and there are a few places where it would be useful (e.g. the df collector where we store mount points). To keep the implementation simple, we'll probably also allow / in metric names and tag names a I believe they share the same validation regexp.

Is there any reason this could not be implemented? It seems to be a one-line change in src/core/Tags.java. I've tested it on my branch and works fine, but there may be corner cases I'm not aware of.

The only other place that would need changing is the UI, which seems to do input validation. I'm not quite sure what file to modify for that.

This is a very simple issue indeed. Probably a 2-3 line change. As you noted, validateString in src/core/Tags.java needs to be updated and the validation regexp in the UI are in src/tsd/client/MetricForm.java. I think that's all that needs to be done. Feel free to propose a patch, I'll be happy to review it and integrate it.

Allow `/'in tag and metric names.
