[WIP] Get translations from transifex (#615)

* Cleanup extract_strings in preparation for using transifex
* Re-enable support for V1 style language files
* Use .po translation files instead of old lang.xx files.  Support upload/download from transifex
* Add BOM to lang files.  Properly escape strings from po files
* Add utlities to clean translations for auto-merge
* Revert use of elffile for string generation because it is too optimized
* Fix string length parser to properly handle V2 files
* Remove PHONY elf target
* Included updated translations from transifex
