Include module name for area summary stats 
The PR prints the name of the module when displaying the final area count.

Pros:
- Easier for the user to `grep` for area information about a specific module

Cons:
- Arguably more verbose, less "pretty" than author desires

Verification:

92eb841f0a Value of properties can be expression. 
Example found in the 2007.03 Liberty Reference Manual that was also found
in the wild:

    input_voltage(CMOS) {
        vil : 0.3 * VDD ;
        vih : 0.7 * VDD ;
        vimin : -0.5 ;
        vimax : VDD + 0.5 ;
    }

Current implementation just parses the expression but no interpretation is done.
