* OmdbProvider: The result often contains strings like '2010-' or
'2010-2012'. I fixed the parsing to use the first 4 digits only in these
cases
* TheMovieDb: While the search method did send appropriate queries for
different search types, it didn't differentiate for deserialization of
results. I fixed this at least for the TvResults, in order to get the
'first_air_date' property parsed.
* TheTvdb: The parsing of the 'FirstAired' node was missing here as
well (for search results)
In my configuration, the Omdb provider is the first in the list for
movie metadata. This was the default at the time I installed MB and I
never changed that (don't know what the current defaults are for a new
installation).
When I use the identify command for movies in the metadata editor, I
always get a single result only. This is due to the fact that the Omdb
provider used the title API with "t=moviename", while there is also a
search api with "s=moviename" which will return multiple results.
This commit modifies the OmdbItemProvider to use the search API variant
and enable returning multiple results
