Bug fix for missing import

• Fixes issue #23 , missing sys module import for acreate.

Workaround for single column CSV file

The Python CSV sniffer gets confused when it has to deal with a CSV file that has a single column only. As a workaround, there is now an option for arange and aenv to switch off the sniffer, which is probably not required for such a simple data format.

Bug fix for log file locking problem

Accidentally, an deprecated API for file locking was used, resulting in an intermittent bug causing some log entries not to be written. Replaced by current API calls.

Fix for installation

The installation would omit some Python files, thanks @wpoely86 for spotting this, and submitting the pull request.

Release with Makefile.in

Apparently if you delete a release, do additional commits, and create a release with the same name, the changes are not taken into account.

Now with autotools artefacts included.
