netsurf/riscos/gui.c
Vincent Sanders 67ded2a02a This moves message loading out of netsurf_init into each frontend 
The translated message loading is dependant on configuration of
resource location in each frontend, additionally they should have the
ability to deal with errors in this loading in a implementation
specific manner.

This also extends the message loading API to be capable of loading
from an inline memory buffer instead of from a file.
