* Reworked the parsing at npc.c.

- Fixes npc.c discarding the '}' at the end of file, when there is no newline. (uncovered as a side-effect of r11487)
* Empty script functions always have code now (won't report as missing when you try to call them).
* Changed userfunc_db to not limit the name to 50 characters.
