Make props insensitive to case

[#1]

Make props perform in a similar manar to eVars when it comes to the case of a value.

In other words, props should be insensitive to the case of a passed value.

Example:

prop1 = "myValue"

prop1 = "myvalue"

prop1 = "Myvalue"

Under the report for prop1 we should see myValue = 3.

I think this should be more of an option rather than a requirement since sometimes myValue needs to be separate from myvalue
