IDE Property Editor for Custom Properties error

[Paul Dupuis]

This bug probably won't impact many people, but I just reported bug 
https://quality.livecode.com/show_bug.cgi?id=23712

In older versions of LC you could have custom property keys that had 
commas in them, such as a key like "topic,subtopic" for a online help 
system. The current (and recent) property inspect tries to convert 
custom property keys with a comma into arrays! Just thought I would 
raise this on the list for anyone else who might be impacted.
