Update wxLua for Linux and OSX builds

[drahosp]

I just finished updating wxLua 2.8.10.0 so it builds with wxwidgets using the updated CMake macros. This allows me to port it to Mac and Linux as we no longer require the native buildsystem. So I'm opening this issue as not forget about it while working on #49.

• Update current builds for OSX na Linux
• Update wxLua to 2.8.12.2

What by chance would be the status of this? I'd love to use LuaDist, but I need wxLua :(

Full "from source" solution should be ready next week, @kapecp is working on new CMake builds for wxWidgets. In the mean time I can use binaries of wxWidgets not generated by LuaDist to push it out sooner. This issue is now our top priority.

so, is it working now?
