luci-app-privoxy: modified to support new LuCI structure

* Makefile
    - modified to support new LuCI build structure when building i18n support
    - increase "patch" version
* privoxy.lua detail.lua apperror.lua
    - modified version detection
    - removed function ipgk_version()
* new file build/i18n-po2lua.pl
    - copied from luci build system to create lmo language files
