Added the 22x22 and 32x32 versions of the list-remove oxygen icon.

Replicated spectrum IDs are now shown in the spectrum list GUI element.

Created generic_fns.spectrum.replicated_ids() to create a list of replicated spectrum IDs.

A spectrum ID is given, and all spectra which are replicates of it will be returned as a list.

Created the replicated_flags() method for returning a dictionary of replicated spectra flags.

The spectrum list GUI element noe_spectrum_type() and relax_times() methods now return correctly.

They now return True if a column has been added.

The spectrum list GUI element now displays relaxation delay times if set.

Renamed update() to build_grid().

Removed a number of variables from the base relax_gui object in the relax data store.

These include:
ds.relax_gui.unresolved = ""
ds.relax_gui.table_residue = []
ds.relax_gui.table_model = []
ds.relax_gui.table_s2 = []
ds.relax_gui.table_rex = []
ds.relax_gui.table_te = []

Deleted the entire gui.analyses.relax_control module as it is completely unused.

Eliminated the global parameters data store object and GUI window.

This concept severely limits the GUI's flexibility and usefulness and is to be replaced by either
analysis specific GUI elements within the analysis pages, or by direct access to the corresponding
user function. For example specifying 'newton' optimisation is useless for the R1 and R2 as only
simplex can be used, or the NOE as no optimisation is performed.
