* Improve error handling in lua interpreter.Robert Vollmert2009-11-031-4/+1
| | | | | | | | | lua_pcall is now passing 0 for errfunc so the plain error message comes out. Also, remove the call to lua_gc on error since that was causing further errors. This is probably not the right way to do things but hopefully an improvement for now.

* Luaterp: introductory comments and renaming.Robert Vollmert2009-10-281-2/+8
| | | | | | | | To use, set "delay_message_clear = true" and call wizard mode Ctrl+T. To echo return values from statements, prefix them with '=' and define the global __echo. (__echo = crawl.mpr will work for single return values.)
