Execute a string as LUA code.

RunScript("script")
== Parameters ==
=== Arguments ===
:("script")

:;script : String - The code which is to be executed.
=== Returns ===
:<i>nil</i>

== Example ==
:To define a function dynamically you could do:

local retExpr = '"Hello " .. UnitName("target")';
RunScript("function My_GetGreeting() return " .. retExpr .. ";end");

==== Result ====
:The My_GetGreeting() function will be defined to return Hello followed by the name of your target.

== Details ==
: This function is NOT recommended for general use within addons for a number of reasons:

: 1. It'll do whatever you tell it, that includes calling functions, setting variables, whatever.

: 2. It does things globally, so to get data out of it you have to pollute at least one global variable. This isn't a big deal but it's mildly annoying.

: 3. Errors in the script string produce the error popup (at least, they produce the UI_ERROR_MESSAGE event).

: On the other hand, it's invaluable if you need to run arbitrary code, or do self-generating code.
