netsurf/riscos/theme.c
Daniel Silverstone 6807b4208a Remove the netsurf/ from the include paths and rationalise use of <> vs "" in includes 
NetSurf includes are now done with ""s and other system includes with <>s as C intended.
The scandeps tool has been updated to only look for ""ed includes, and to verify that the
files exist in the tree before adding them to the dependency lines. The depend rule has
therefore been augmented to make sure the autogenerated files are built before it is run.

This is untested under self-hosted RISC OS builds. All else tested and works.
