[jcifs] Problem (and fix) accessing file contents using smb: url

[Michael B Allen]

There's a mime.map file in the jar. Look at
jcifs/http/NetworkExplorer.java for how it comes up with the Content-Type.

But your fix should be added too I think. I'll add it to TheList [1].

[1] Note that I just processed The List so it will likely be another
year or two before this fix reaches mainline :-<
