Add total tables adding all signatures for a crash

[pascalchevrel]

For bugs with multiple signatures, it can be sometimes hard to evaluate the total number of crashes involved when they are scattered across a bunch of signatures with low crashes.

Here is a mockup of what it could look like

Example of bugs where it would be useful:
https://bugzilla.mozilla.org/show_bug.cgi?id=1464938
https://bugzilla.mozilla.org/show_bug.cgi?id=1465556

Maybe this could be triggered when the number of signatures is > 5

Your reasoning is correct when all the signatures in the bug are relative to the same root cause.
But sometimes a patch is fixing some signatures and not some others, so it means that the patch doesn't cover everything or the non-fixed signatures are another issue.
But I understand your point and maybe we could add a button or anything else to have global stats when the user want to have them.
