math/R-DBI: Update to 0.7

Notable changes since 0.3.1:
- dbGetInfo() gains a default method.
- New generic dbBind() for binding values to a parameterised query.
- DBI gains a number of SQL generation functions.
- dbDataType() maps character values to "TEXT" by default.
- The default implementation of dbQuoteString() doesn’t call
  encodeString() anymore.
- Deprecated dbDriver() and dbUnloadDriver().
- Import updated specs from DBItest.
- Require R>=3.0.0.

Log message:
Update to 0.3.1

Upstream changes:
# Version 0.3.1

* Actually export `dbIsValid()` :/

* `dbGetQuery()` uses `dbFetch()` in the default implementation.

# Version 0.3.0

## New and enhanced generics

* `dbIsValid()` returns a logical value describing whether a connection or
  result set (or other object) is still valid. (#12).

* `dbQuoteString()` and `dbQuoteIdentifier()` to implement database specific
  quoting mechanisms.

* `dbFetch()` added as alias to `fetch()` to provide consistent name.
  Implementers should define methods for both `fetch()` and `dbFetch()` until
  `fetch()` is deprecated in 2015. For now, the default method for `dbFetch()`
  calls `fetch()`.

* `dbBegin()` begins a transaction (#17). If not supported, DB specific
  methods should throw an error (as should `dbCommit()` and `dbRollback()`).

## New default methods

* `dbGetStatement()`, `dbGetRowsAffected()`, `dbHasCompleted()`, and
  `dbGetRowCount()` gain default methods that extract the appropriate elements
  from `dbGetInfo()`. This means that most drivers should no longer need to
  implement these methods (#13).

* `dbGetQuery()` gains a default method for `DBIConnection` which uses
  `dbSendQuery()`, `fetch()` and `dbClearResult()`.

## Deprecated features

* The following functions are soft-deprecated. They are going away,
  and developers who use the DBI should begin preparing. The formal deprecation
  process will begin in July 2015, where these function will emit warnings
  on use.

    * `fetch()` is replaced by `dbFetch()`.

    * `make.db.names()`, `isSQLKeyword()` and `SQLKeywords()`: a black list
      based approach is fundamentally flawed; instead quote strings and
      identifiers with `dbQuoteIdentifier()` and `dbQuoteString()`.

* `dbGetDBIVersion()` is deprecated since it's now just a thin wrapper
  around `packageVersion("DBI")`.

* `dbSetDataMappings()` (#9) and `dbCallProc()` (#7) are deprecated as no
  implementations were ever provided.

## Other improvements

* `dbiCheckCompliance()` makes it easier for implementors to check that their
  package is in compliance with the DBI specification.

* All examples now use the RSQLite package so that you can easily try out
  the code samples (#4).

* `dbDriver()` gains a more effective search mechanism that doesn't rely on
  packages being loaded (#1).

* DBI has been converted to use roxygen2 for documentation, and now most
  functions have their own documentation files. I would love your feedback
  on how we could make the documentation better!
