Check directory on uploads

For historical reasons, slweb used to check for a name called "dir" on
multipart/form-data POST requests. However, stricly speaking this is
application logic, so it has been now moved from slweb to slcl.

This has resulted in a couple of breaking changes in slweb that had to
be updated on slcl.
