Better support for encoding

[arunsrinivasan]

One way to provide better Encoding support is to provide an argument while creating/converting a data.table. That is,

data.table(..., encoding = c("unknown", "UTF-8", "Latin-1"))
as.data.table(..., encoding = c("unknown", "UTF-8", "Latin-1"))
setDT(..., encoding = c("unknown", "UTF-8", "Latin-1"))

Since we convert the i argument of joins to data.tables, even scenarios of vectors/lists are handled. This should drastically reduce the occurrence of encoding warnings.

It would be good to improve the situation with respect to merging on columns with marked encodings. The current warning message is leading to nonsense like http://stackoverflow.com/q/33482308/189946
