Improve dsl exception readability

Browse Source 
Improve dsl exception readability by double quoting names
of classes, properties, and methods mentioned in the exceptions.

Since property names are often lowercase strings (like 'find' or
'environment'), it can be very hard to distinguish a
property name from general exception information in the
error message (especially for someone new to MuranoPL).
This commit improves this situation, by explicitly highlighting
(quoting) the property in question.
