Different SMS queues with different priorities

Hello,

thank you for the awesome work you've been doing in httpSMS.

A feature request I'd like to propose is to be able to prioritize queues for sending SMS-es.

For example, I have a normal queue and there are 100 SMS waiting to be sent. If I have another SMS that needs to be sent urgently I'd need to wait for those 100 SMS to be sent.

I'd be really useful if we have an "urgent queue" where we will be able to send SMS that needs to be sent ASAP, or give a "priority" number from 1 to 10 when sending an SMS.

As far as I am aware there is no solution for that now.

Thank you!
