Yara index creation fails when local rule has syntax errors.

Hi,

It seems if you create a new Yara rule from scratch, and then restart pastehunter, you get the message below. If you remove the new Yara rule then the restart works.

It may be related to this error message:

That looks like the issue is with the syntax in your local rule file.
I will add some more handling around yara rules to validate each rule before including so it doesnt take the whole stack down.
