NRE when no footer is given

[Alloc86]

Hi,

first of all: Great plugin! Easy to use and exactly what I needed :)

Just stumbled on a minor issue: When using this plugin as a pipeline step and leaving out the "footer" parameter you get a NRE:
java.lang.NullPointerException at nz.co.jammehcow.jenkinsdiscord.DiscordPipelineStep$DiscordPipelineStepExecution.checkLimitAndTruncate(DiscordPipelineStep.java:143) at nz.co.jammehcow.jenkinsdiscord.DiscordPipelineStep$DiscordPipelineStepExecution.run(DiscordPipelineStep.java:133) at nz.co.jammehcow.jenkinsdiscord.DiscordPipelineStep$DiscordPipelineStepExecution.run(DiscordPipelineStep.java:111) at org.jenkinsci.plugins.workflow.steps.AbstractSynchronousNonBlockingStepExecution$1$1.call(AbstractSynchronousNonBlockingStepExecution.java:47) at hudson.security.ACL.impersonate(ACL.java:290) at org.jenkinsci.plugins.workflow.steps.AbstractSynchronousNonBlockingStepExecution$1.run(AbstractSynchronousNonBlockingStepExecution.java:44) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

Can easily be worked around by supplying an empty string, but it would obviously be nice if the plugin didn't freak out if you just omit it :)

Regards,
Chris
