Teach the emacs mode to compile yecc and leex files
If visiting a .yrl or .xrl file in emacs with erlang-mode, then the `erlang-compile' function (normally bound to C-c C-k), now knows how to compile yecc and leex files, and then, if that compilation succeeds, also compiles the resulting .erl files. Also introduce a `erlang-compile-command-function-alist' to make it possible to hook in other functions for computing compilation commands/expressions, depending on file name.
