DEB_out. Fixed issue with missing "WARNING" and line feed in warning messagss. Made DEB_error text red in HTML, but not BLINKing as such is deprecated HTML sadly. 

 Added DEB_set_double_format() DebController mechanism.

 Renamed two callstack indent() functions get_indent() for clarity.

 Some cosmetic refactoring in accordance with ReForm coding standard (param names).
