scala doesn't take -D properties on WIN7

[scabug]

scala -Dprop=value -e "println(System.getProperty("prop"))"

output

null

this problem does not appear on Linux or Mac

This pull request scala/scala#1957 based on the 2nd attachment to this bug did not address all the issues. From the pull request discussion:

• While this parses the -D and -J options, they also get passed as arguments to the class that is run in the end (and I expect that trying to fix this would make the other problems much worse)

• Quoted -J options are silently dropped

• Single-quoted -D options are silently dropped

• Double-quoted -D options are either silently dropped or result in an error

I just tested my patch with the -e "println(System.getProperty("prop"))" argument and my patch does not work on that... I guess I'll give it another try later.

Turns out fix wasn't complete. See discussion on the pull. I'm kicking the fix version and assigning to community since I don't have a working Windows environment for development.
