[Suggestion] Add Number of results found in "Variables Overview" view

[anefzaoui]

e.g. http://transvision.mozfr.org/variables/?locale=ar&repo=gaia
I'd like to see how many results are shown so after I fix the mistaken variables and refresh I can see the new number and know there has been a difference.
This is useful especially when the number of errors is big.

Can I take this issue ?
