This unifies wr_vic and wr_minic in a single directory,
which results in a simplification of Makefiles.
EXTRA_CFLAGS has been removed as it's now not needed any more.

This commit cleans up the Makefiles, removing the "build.sh"
scripts and adding EXTRA_CFLAGS to include wr_vic.h from
wr_minic directory.  This works, but the next commit
works better.

This is a simple copy for files from the white-rabbit svn,
currently at revision 623. No local modification is there
at this commit. The author of the code is Tomasz Wlostowski,
even though I haven't marked him as --author (lazy me).
