Airtable

* Fixed a bug that prevented records returned from select queries
from being deleted.

* Fixed the demo page (test/test_files/index.html)

* Added `Table.select` for querying records in a table. It takes the
following optional parameters for sorting and filtering records:

fields: only include the specified fields in results.
filterByFormula: only include records that satisfy the formula.
maxRecords: at most, return this many records in total.
pageSize: at most, return this many records in each request.
sort: specify fields to use for sorting the records.
view: return records from a specific view, using the view order.

* Deprecated `Table.list` and `Table.forEach`. Use `Table.select` instead.

* Renamed Application to Base. This is a breaking change for the client, no changes in the API.

* Added ability to listRecords according to view (filters and order) and sort by a field.
