Suggestion: allow more temporary files on shared folder

[DetlevCM]

In a previous installation of the OpenSemantic Search server, I noticed that a lot (nearly 200.000 I think) files were written to the temporary directory during the import and analysis of documents. As a result, the size of the VM increases, which is not ideal for those with laptops and limited SSD space. (Yes, the disk can be compressed, but it is a bit of a hassle.)

The project would be improved, if these write intensive operations could be carried out on a shared folder which will not impact the size of the virtual machine.

As a side note: without the named entity recognition and the graph DB, the VM is sitting happily at roughly 9.5GB and not growing in size (yet).

Though I use it for searching my local papers, so some of the more sophisticated features are of limited use to me.
