Allow End of Line Comments in CODE Definition

This change permits end of line commnents on CODE definitions to be carried through the the mhp file.

Specifically, and likely most usefully, this allows #noloop commands to be respected at the end of CODE defintions such as:

```
CODE, $garage_door->tie_event($garage_light->set(ON), ON); #noloop
```
