Addition of the relax status singleton object.

See https://mail.gna.org/public/relax-devel/2010-01/msg00094.html and other related posts in the
thread.

The idea is that various parts of relax deposit status information into here that other parts of
relax can then use. For example the Monte Carlo code can place the current simulation number in
there while the relax GUI controller can read these values.

Doublication of reading in the pipe parameter was removed.

Limited Monte Carlo number was removed.

This was only used to thest the progress bar of the controller.

Proper dublication of spectra was achieved.

Formatting error in read_intensities was removed.

Python modules time and os.sep are loaded into the script.

Output file are better labled.

E.g. a R2 output file at 600 MHz will be 'r2_600.out'. In addition. grace will not open automatically after the calculation.

No spins are deselected if no spins / residues are indicated.

A fix has to be done if spins /residues are deselcted. Best will be to create a file listing these residues / spins.

Replicated spectra are set correctly.

Relaxation times are converted into float objects (from strings).
