Properties with "." in the name are not accessible

Due to the check for dots in the name of a property at below code location, properties that have one or more dots in its name are not accessible to users of the library.

I wonder if this by intention or if this is a bug? I ran into this issue because story points are stored in a property called com.ibm.team.apt.attribute.complexity and I wasn't able to find it using rtcclient even though it was visible in the raw response from RTC.

Once I comment out this code location I can access the story points.
