#189 TaurusPlot save config problem with models

[Carlos Pascual]

(from an email to devel list by jmoldes)

There is a problem when saving the models of a taurusplot in a configuration
dictionary.

If you use a model which device name includes capital letters then this model
is not saved.

Find below a possible patch (maybe it is better to make sure that both
"curvenames" and models are always lower case: I leave this to tauruslib core
developers)

Fixed using a slightly different approach (casting curvenames list to a CaselessList)
