- template parser: merge lmo library - template parser: rewrite to operate on memory mapped files - template parser: implement proper line number reporting on syntax errors - template parser: process translate tags directly and bypass Lua - template lmo: introduce load_catalog(), change_catalog() and close_catalog() - template lmo: rewrite index processing to operate directly on the memory mapped file - template lmo: implement binary search keys, reducing the lookup complexity to O(log n) - po2lmo: write sorted indixes when generating *.lmo archives - i18n: use the template parser for translations - i18n: stub load(), loadc() and clear() - i18n: map setlanguage() to load_catalog()
