NF: allow expInfo fields to be ordered, required, hidden and deprioritised using name syntax

[TEParsons]

From docs of parsePipeSyntax function:

Pipe syntax is as follows:

    |req = Required input
    |cfg = Configuration parameter, hidden behind "read more" tag
    |fix = Fixed parameter, meaning its value can't be changed
    |hid = Hidden parameter, meaning it's not down by DlgFromDict
    |0, |1, |2, etc. = Parameter with specific place in key order

An unescaped * in the key is considered shorthand for |req.
