[scm] Need perm changes for trustin owned files on remote repo

[Alex Karasulu]

Hiya Trustin,

Got snagged again with perm issues on the remote snapshot repo.  Can you 
massage the remote repo when you get a chance?  I might ask infra for 
now but please make sure you have directoryPermissions and 
filePermissions tags like in the following setup in your settings.xml:

<?xml version="1.0" encoding="UTF-8"?>
<settings>
 <servers>
   <server>
     <id>apachecvs</id>
     <username>***</username>
     <privateKey>/home/***/.ssh/id_rsa</privateKey>
     <directoryPermissions>775</directoryPermissions>
     <filePermissions>664</filePermissions>
   </server>
 </servers>
</settings>

If you already have this then we have problems :(.

Thanks,
Alex
