Task with mask mode does not support custom mask flags

[BenKettlewell]

I created a task with a custom mask mode.

When I ran it against a known SHA1 hash it appeared to run successfully with the command below but failed to crack the hash and took only about 5 seconds so it's definitely not working. To validate I didn't have something else screwed up I removed the custom part and it cracked it instantly.

I believe the problem is formatting according to here.

I believe hashcat requires having the custom masks before the hash file.

Dang this might not be as quick of a fix as I initially thought. Either we'll have to 'know' that the user entered in a custom char set, or provide an option for the user to type in a char set with a new text field. Not sure what is the best solution.
