Don't use luaL_error in luaA_object_emit_signal (FS#713) 

This function can be called from unprotected contexts. Calling luaL_error() in
this case results in a call to luaA_panic() and awesome dies.

The only real change here is that this now calls warn() instead of luaL_error().
The rest is reindentation because warn() returns while luaL_error() didn't.
