Feat: Add Effect Queue Length variable

[codehdn]

Description of the Change

I've added a new text variable "effectQueueLength" as a utility variable. This variable takes in a queue name

Applicable Issues

#2513

Testing

• Setup a new effect queue call it "testing" make it whatever queue mode you like
• disable the effect queue
• Setup a command and call it !addtoqueue with an effect of Chat that says "hi"
• In the !addtoqueue command set the queue to be "testing"
• Setup a command and call it !queuelength with an effect of Chat that says "$effectQueueLength[testing]"
• Setup one more command and call it !badqueue with an effect of Chat that says "$effectQueueLength[not-a-real-queue]"
• Now head to the dashboard
• send a message of "!addtoqueue" which will bring the queue count to 1
• send a message of "!queuelength" it should return a queue length of 1
• send a message of "!addtoqueue" 3 times the new queue length should be 4
• send a message of "!queuelength" it should return a queue length of 4
• head over to the effect queues page and enable and re disable your queue
• head back to the dashboard
• send a message of "!queuelength" it should return a queue length less than 4 (exact number will depend on queue type and how long the queue was enabled, anything below 4 is a passing condition)
• send a message of "!badqueue" this queue does not exists and as such should return the text "Unknown"
