Zeiss LSM: preserve wavelength range for spectral detectors

[mlinkert]

Channels acquired using a spectral detector ('ChS') have a range of wavelengths associated with them (see '*Wavelength Begin' and '*Wavelength End' in original metadata).

It would be nice if these values were preserved somewhere in OME-XML, though I don't know at the moment where best to put them.

I think we already do this in some cases by creating a 'Filter' that represents a spectral detector.

E.g. Model: "SP Mirror 1", TransmittanceRange (CutIn & CutOut) etc. This could be improved by specifying a new FilterType? to indicate this is a tuneable filter. Since we currently only have:

omero=# select * from filtertype;
 id | permissions |     value      | external_id 
----+-------------+----------------+-------------
  1 |         -35 | LongPass       |            
  2 |         -35 | ShortPass      |            
  3 |         -35 | BandPass       |            
  4 |         -35 | MultiPass      |            
  5 |         -35 | Dichroic       |            
  6 |         -35 | NeutralDensity |            
  7 |         -35 | Other          |            
  8 |         -35 | Unknown        |

I will add a new filter type "Tuneable" at the moment. Extending the detector can be looked at as part of ticket #3682 - I have added a link back to this ticket.

After consulting with Helen, the office, and google we have decided the spelling is "Tunable" (without the e from Tune).

[ajpatterson]

Adding attribute "Tuneable" (with the e) as stop gap measure so that the spelling matches that used in Laser. Either it will remain as this spelling or we will changes the spelling for both Filter and Laser.
