render tabs as "TAB" in the command-line and in SciTECO macros

* This requires the new SCI_SETTABDRAWMODE(SCTD_CONTROLCHAR).
* It makes no sense to let TAB indent in TECO code as it can be
  the insert-with-tab command (^I).
  On the other hand large `I`-blocks could include TABs which are
  actually meant as indentations.
