CRAN submission

Summary

This release contains a major refactoring of the R layer.
Following functions has been dropped:

• "dbApply" has been dropped, as it was not implemented and currently there are no plans to pursue this approach.
• "dbListConnections" has been dropped as it is marked DEPRECATED in DBI package.

Important: The bundled ODBC driver for Linux/Mac was removed (as CRAN requires to remove any binary executables from the package); dbConnect("exa",...) now will look in some default folders for the driver, please check the README for more details.

Also, this release now support the data visualization in the RStudio connection pane.
