AZTEC: add almost optimal encoding algorithm, previous algorithm

Browse Source 
available via "--fast" (input_mode |= FAST_MODE) (ticket #347);
  add new option "--azfull" (option_3 = ZINT_AZTEC_FULL) to only
  consider Full symbols (not Compact ones) on automatic sizing
GUI: adjust Aztec tab to show feedback by selecting combos and
  shorten message to just actual ECC;
  grpCodabar min width
library: debug source input dump 200 -> 2000
common: some code fiddling (c -> ch, flg -> flag)
backend_tcl: add "-azfull" option & make capitalization of
  help more consistent
general: remove some trailing whitespace
manual: make Aztec ECCs more precise, i.e. ">=" rather than ">"
  (similarly in GUI)
CLI: code fiddling c -> opt
