read-only users access configuration for subversion repositories and granularities

Virtualmin generates automatically subversion access files in the etc subdir of the virtual server:

svn-access.conf and svn.basic.passwd

However all users have in it " = rw" read and write access.

And all have: [projectfolder:/]

• It would really help to be able to give only read access to certain users to avoid user errors.
• It would be really cool to be able to be able to set optionally more granular accesses to subfolders, to avoid having to create many repositories, and have one revision numbering instead of many.

Second request is less urgent than first one, but would be cool too.
