Perhaps it was wrong to tie the UI issue in with this.  If we want a patch to
disable compression when using netscape 4, I can prolly churn that out in no
time.  In the meantime, I just disabled compression completely in view.php.

There is the issue, however, that the "view" link is what (our) users see and
use for most any interaction with attachments, which can create some undesired
results (like the gzip compression getting invoked on files the browser can't
display, or people using "view" to download files, and getting stuck w/the name
"view.php" for their attachements).

Maybe there should be two links, clearly labeled "View" and "Download", and not
make the filename a link at all?  I kinda think that "view" should be disabled
except in situations where we know the browser can display the file - either
because it's a file format the browsers can handle natively (mostly graphics),
or because there's a mime_viewer registered with horde.
