Script / TextList Editor 60% done

-Added support for bot variables like $mp, $cap, $mppc (same of Neobot
:D)
-Added support for changing '&', '\n', '<', '>' in scripts so now you
can save them
-Added lua_toString() for the ScriptEditor (so now they load :D)

-TO DO:
-->assign $BotVariables ($mp,etc) to their Delphi function.
-->Syntax colours as Neo had for its scripts
-->add multithreading support for scripts/healrules
-->Sandbox the lua cmd as Neo due to security reasons
