[Owncloud] Regarding file attributes and that they are writable by group.

[Stefan Eriksson]

I have posted this before but see that the official 4.0 release still have
the same file attributes:

File "index.php" is writeable by group

I fixed it with:

find /dir/ -type d -exec chmod 755 {} \;
find /dir/ -type f -exec chmod 644 {} \;

but I dont know if its a design choice or if its a bug? I personally dont
see a point in why foldes and files are all writable by group?
