Support specifying field data type in Excel, csv, txt, tab data sources

Idea created by curtvprice Champion on Nov 1, 2011
    An annoyance of using file-based tabular data is the inability to define the data type of the input fields. Fields that "look like" numbers always come in as numbers.

    The only way around this (mentioned in KB article 31793) is to create dummy rows of data.

    There really should be a more direct way of doing this without resorting to "fooling" the software by putting in dummy data values!
