Changes for navigator 1.2

[mmcclenn]

In order to get Navigator using 1.2, the following changes need to be made to the data service:

• fix strata/auto with limit

[vjpsyverson]

• occs/list needs to always report tna (accepted_name)

[mmcclenn]

It is not possible for occs/list to always report 'tna', because the taxonomic name to which the occurrence has been identified may not actually be in the taxonomy table. Solution: when 'tna' is not available, use 'idn'.

[vjpsyverson]

• colls/summary does not accept interval_id=0 although Navigator tries to pass it -- should it? (example)

[vjpsyverson]

strata/auto appears to now ALWAYS set limit=10 and just doesn't accept the parameter anymore. Solution: stop trying to pass it
