(math/R-DBI) Updated 1.0.0 to 1.1.0

# DBI 1.1.0

## New features
- New `DBIConnector` class (#280).

- Specify `immediate` argument to `dbSendQuery()`, `dbGetQuery()`,
  `dbSendStatement()` and `dbExecute()` (#268).

- Use specification for `dbGetInfo()` (#271).

- `dbUnquoteIdentifier()` now supports `Id()` objects with `catalog`
  members (#266, @raffscallion). It also handles unquoted identifiers
  of the form `table`, `schema.table` or `catalog.schema.table`, for
  compatibility with dbplyr.

## Documentation
- New DBI intro article (#286, @cutterkom).

- Add pkgdown reference index (#288).

- DBI specification on https://dbi.r-dbi.org/dev/articles/spec now
  comes with a table of contents and code formatting.

- Update examples to refer to `params` instead of `param` (#235).

- Improved documentation for `sqlInterpolate()` (#100). Add usage of
  `SQL()` to `sqlInterpolate()` examples (#259, @renkun-ken).

- Improve documentation for `Id`.

## Internal
- Add tests for `dbUnquoteIdentifier()` (#279, @baileych).

- `sqlInterpolate()` uses `dbQuoteLiteral()` instead of checking the
  type of the input.

- Avoid partial argument match in `dbWriteTable()` (#246, @richfitz).
