More descriptive push notifications

Right now, if the printer has any issue whatsoever, it simply sends a "printer needs attention" message. Some of these are genuine things that need attention (like nozzle cleaning failed) and some are simple things that don't need my attention (like the top grill needing to be opened) Instead of sending "printer needs attention" it would be far more useful to state what the issue is, so for example "ISSUE: Core one nozzle cleaning failed" or something along those lines.
