Code generate TextLoader API and enhance it with convenience API. (#142)

*Code generate support for IDataLoader *Make TextLoader API code generated so that it's at functional parity with the text loader in the ML.Net infrastructure. *Move TextLoader API under Microsoft.ML.Data namespace *Add convenience TextLoader API. *Add error checking for invalid loader arguments such as ordinal, column names. *Update baselines. *Update samples with new loader API and backward compatibility with old loader API.
