wx3.0: compilation fix for arch linux

* Manually cast WxGetTranslation
* Accept string as format parameter of pxWindowTextWriter
* Manually convert wxString to wide string

Note: Wx setup.h is not the same between Debian and Arch. Unfortunately it
generated various compilations errors on wx code.

Close issue #172
