relax SVN archive

The relax save and results XML files now include subversion details in the <relax> tag.

This indicates the repository version and the URL, allowing for better debugging.

Bug fix - the 'relax --version' print out now works from any directory.

This was only working if relax was being run from the installation directory!

The 'relax --version' print out now includes the full subversion info, if it is a checked out copy.

The relax_data.delete user function is now finally properly implemented!

This was reported by Martin Ballaschk <ballaschk att fmp-berlin dott de> as bug #19785
(https://gna.org/bugs/?19785), and the mail message at
http://www.mail-archive.com/relax-users@.../msg01183.html (Message-Id:
<EED32F2B-B78F-4D23-9E0B-3DDE8B661F48@...>).

The problem was that this was not being checked by the test suite, and no one had tried to delete
relaxation data before (well, at least it was never reported).

Added checks for the proton frq for the relax_data.read and relax_data.back_calc user functions.

This is in response to the problems seen by Martin Ballaschk <ballaschk att fmp-berlin dott de> and
reported at http://www.mail-archive.com/relax-users@.../msg01179.html (Message-Id:

If the frequency is not exact or is less than 1 MHz, warnings are now given to the user.

Improvement for the model-free auto-analysis in the GUI.

After execution, the main data pipe of the analysis tab is now set to the 'final' data pipe
generated by the dauvergne_protocol. This means that when switching between analysis tabs, that
going back to the model-free tab will make the 'final' data pipe the current one, rather than the
data pipe used to initialise the analysis.
