ignore folder (.svn) when building

In CoronaSDK 2011.591, when it is building, the console log output the following message:

Copying /Users/steven/Documents/Corona/Test/assets/.svn/text-base/test.png.svn-base to /Users/steven/Desktop/Test/assets/.svn/text-base/test.png.svn-base
Actually, if every files under a folder name started with “.” are ignored should be fine.
