[Feature Request] Filter empty subjects, comments, etc..

[ghost]

Filtering by subject, comments, etc. works great, but you still got stuck with all threads leaving the field in question empty. As regex filtering for empty strings doesn't seem to work, I'd suggest adding an "empty" checkbox.

Is this a similar concern as chandevel#744?

I guess it's pretty much the same issue. Considering it's still up, is this harder to fix than it looks like?

Regular expressions that match the empty string (like /^$/) should now work in dev. Note that any expression that would reduce to a pattern input of empty string (like //, "", or any number of spaces) have been prevented, as those would match everything.

Ah, I'm just on the regular version, thanks for your efforts!
