Title: Adding custom placeholders through token expression in mask.

Allows you to quickly define a customer placeholder using "{<CHAR>}" expressions that immediately follow valid mask definitions.

Example:

// Setting mask to:
mask = "9{M}9{M}/9{Y}9{Y}"; // Creates placeholder "MM/YY" instead of "__/__"

This patch does not affect existing functionality.
