1. Padding to minlength

Discussion on best way to pad to minlength for non-string text 
representations

Decided to split textpadCharacter  into textStringPadChar, 
textNumberPadChar and textCalenedarPadChar so that different defaults can 
be set up for each type,

Decided that all the ICU pattern special characters should be allowed, in 
particular the padding character to allow padding after the sign or 
currency symbol.  Normal dfdl padding will be applied after the pattern 
has been used to generate output item.
