Remove '/' from filename to avoid filepath exception

When a http url has a filename set to something that contains a '/',
pyload will error out when trying to merge the chunks as it sees the '/'
as part of the path.
Example:

HTTP Header contains:

    filename=55/filename.img

Chunks are saved as:

    <path to download folder>/55filename.img.chunk0
    <path to download folder>/55filename.img.chunk1

Exception on merge will complain:

    Error: file does not exist: <path to download folder>/55/

as it thinks '55/' is a subdir
