All of options listed above are added to csv2* and execl2* commands. Backend transformer yet to be modified to support these options (logged as issue #7808).
   -DQ : enable date quote identifier : []
   -SQ : set string quote identifier : single, double, bracket
   -d  : set column separator : default ","
   -l  : set linefeed : default "\n"
   -NT : set null value : default : ""
   -PA : set datetime format
   -PD : set date format
   -PT : set time format
   -c  : set stream encoding = default UTF-8
Option names follow the naming conventions used by \sqlimport and \sqlexport.

Also added a -ED (--enable-date-quote) option, which is mapped to AquaCsvReader/Writer.enableDateQuotedString(boolean) method.

Note that linefeed option (-l) is not applied to csv2excel.

Removed -DQ|--date-quote option from all of csv2* commands. Date quote identifier is hard-coded to '[]' in reader and custom identifiers are not allowed.  SVN r29846.

Verified in 12.0.1-2. Tested the new options.
