Move TCL-specific code into script.c
Adapt TCL to bd::ScriptInterp
Add newline for TCL results over cmd_tcl
Avoid calling tcl_eval() twice
Init script functions on load
Refactor tcl_eval() into script_eval()
Refactor script commands into irc.mod/script.c
Add script 'chanlist'
Use a table for loading commands
Use dumplots() for sending back TCL response
Update for generic bdlib return types
Fix script_chanlist for 'b' flag to be eggdrop-script compat
Match all on flags given

This is actually an eggdrop bug, but let's do it correctly here.
Cleanup code
Move maze
Update TCL symbols
Pass INCLUDES into src/mod
Update scripting to use new pure wrappers
Fix bind_entry_exec() checking the wrong field for BIND_WANTS_CD
First implementation of script binding prototype

This doesn't quite work right as the CD doesn't pass through
and the interp is hardcoded in the event handler
