venue search doesnt work with :near

[kprzywara]

foursquare requires either :ll or :near to be specified. The gem forces a check on :ll presence in venue_proxy.rb so you cannot do :near searches. the code also fails since its expecting 'groups' returned while foursquare returns venues immediatelly.

I monkey patched it this way (extended the if statement and commented out what doesnt work)

def search(options={})
raise ArgumentError, "You must include :ll or :near" unless options[:ll] || options[:near]
#response = @foursquare.get('venues/search', options)["groups"].inject({}) do |venues, group|
venues = @foursquare.get('venues/search', options)
=begin
venues[group["type"]] ||= []
venues[group["type"]] += group["items"].map do |json|
Foursquare::Venue.new(@foursquare, json)
end
venues

  end

=end
end
