DECA-160: matplotlib directory not writable causes stitching error

Description

It seems that stitching aborts if the permissions on the ~/.matplotlib directory are not set properly. Work around would be to manually set permissions on the directory, but it would be nice if the permissions were set by the install script automatically.

The following error is displayed when attempting to run stitching with decapod-server.py:

  Stitching has been removed from the decapod 0.5 release
