creating an SAI called 'none' shows fatal effects

• ARB_DIST can no longer calculate a matrix when no weights are selected

  -------------------- ARB-backtrace 'received signal 11':

• ARB_PARS crashes after startup if no weights selected (similar stack trace)
• some ressource problems in
  • EDIT4/View/ColumnStat and
  • SeqQualityCheck

• change default value for SAI selection list to sth not working as -key (currently it's "none")

[12027] replaces crash by error messages

Awars used for SAI selections:

awar name                              default

AWAR_DOT_SAI                           ""

FA_AWAR_SAI_RANGE_NAME                 ""

two new problems:

• [12027] propagates errors ⇒ using no weights impossible

  aw_message: 'Failed to calculate weights (Reason: Please select a column statistic)'
  

• [12028] does not reset SAI-awars saved in properties (containing 'none'). Check ​them for non-tmp-awars and rename them.
