syntax validation for alert checker conditions

hi, recently i had an issue where in an alert checker, i used "notequal" in an alert checker condition.  when the situation came up, i receive no notification or alert for that checker.  an expert Observium user probably would have seen right away that "notequal" should be "notequals" but this took me weeks to figure out.

obviously, this is my fault, but what surprised me is this syntax error did not result in any visible error to me.  yes, the checker did not fire, however there was no notification that my alert checker had a syntax error in it at all.

I would like to see one or both improvements:

1. an indication in the device alert log.  when the alert checker is run, if there is a syntax error in the condition, then that should be called out so as to alert the user of an issue.
2. a syntax check should be performed at the time a condition is entered to alert the users of a syntax error.
