egg-link not resolved

[mrclary]

Recently, py2app began copying .egg-info and .dist-info files on building application bundles (yeah!). However, when a package is installed in editable mode (i.e. with the -e flag), the .egg-link symlinks are not resolved and therefore the target egg-info is not copied to the app.

The commit above seems to fix the problem for me.

Interestingly, this may also help me track down the lowercase app name in #414, the project that I was using has a subdirectory that contains the distribution that was installed with "pip install -e", and the name of that subdirectory is for some reason used as the name of the app bundle. Very weird...
