Reduction GUI writes files in the home directory

[mantid-builder]

This issue was originally TRAC 10867

Original Reporter: @FedeMPouzols

I just saw that I have a couple of .mantid_... files in my home:

• .mantid_data_sets
• .mantid_last_HFIR_reduction.xml

Maybe there's a good reason for that, but I'd say that these files would be happier in the directory where other mantid files are written, ~/.mantid (bin on Windows), possibly inside subdirectories specific to different interfaces.

You can quickly find where this is done with a grep for the following data members:

• ERROR_REPORT_DIR
• LAST_REDUCTION_NAME
• or more in general, calls to "path.expanduser"
  It seems that the reduction GUI uses the home directory in a few places, and it also seems that this doesn't happen in the other interfaces or anywhere else in the Mantid code.

It looks like this is primarily in some of the SNS and HIFR interfaces, you might want to check and assign on.
