RPC calls now work.

Usage: SENDRPC <user> <type> <message>

Any user may specify a function to call on a certain message type. these
have to be 'bound'.

In scripts put:

rpc <type> <function>

-------------

Example:

[~/.mwrc]
rpc INIT rpc_init

[~/ipc.mws]
SENDRPC Fry INIT "Test"

etc...

Any type not bound will not be called.
