Title: Applied MantisBT #8957: Date Selector for Custom Fields

Based on http://www.mantisbt.org/bugs/view.php?id=8957
Maybe the patch might make it into 1.2.12 this way.
Comparing the files by ignoring whitespace changes makes obvious that only new parts were added (they refer to a new global variable).
