[R] maintenance Apr 2017 (#2237)

Browse Source 
* [R] make sure things work for a single split model; fixes #2191

* [R] add option use_int_id to xgb.model.dt.tree

* [R] add example of exporting tree plot to a file

* [R] set save_period = NULL as default in xgboost() to be the same as in xgb.train; fixes #2182

* [R] it's a good practice after CRAN releases to bump up package version in dev

* [R] allow xgb.DMatrix construction from integer dense matrices

* [R] xgb.DMatrix: silent parameter; improve documentation

* [R] xgb.model.dt.tree code style changes

* [R] update NEWS with parameter changes

* [R] code safety & style; handle non-strict matrix and inherited classes of input and model; fixes #2242

* [R] change to x.y.z.p R-package versioning scheme and set version to 0.6.4.3

* [R] add an R package versioning section to the contributors guide

* [R] R-package/README.md: clean up the redundant old installation instructions, link the contributors guide

It is useful when a 0 or some other extreme value represents missing values in data.}

\description{
Contruct xgb.DMatrix object from dense matrix, sparse matrix
or local file (that was created previously by saving an \code{xgb.DMatrix}).
Construct xgb.DMatrix object from either a dense matrix, a sparse matrix, or a local file.
Supported input file formats are either a libsvm text file or a binary file that was created previously by
\code{\link{xgb.DMatrix.save}}).
