Editing WoW:API SecureCmdOptionParse

{{wowapi}} __NOTOC__

Evaluates macro options in the string and returns the appropriate sub-string or nil
 result, target = SecureCmdOptionParse("macroText")

== Arguments ==
;macroText : a string containing the macro conditions to be parsed.

== Returns ==
;result : The chosen clause text, or no return (nil) if none of the clauses apply.
;target : The [target=(unit)] argument of the chosen clause, if such an argument exist.

== Example ==
 print(SecureCmdOptionParse("[mod:alt] Alt is down; Alt is not down")); -- Prints appropriate text
 print(SecureCmdOptionParse("[target=pet] Cast at Pet")); -- Prints 'Cast at Pet', 'pet'
 print(SecureCmdOptionParse("[nomod,mod] Alt is not down")); -- Prints nothing (nomod and mod cannot both be true)

== Details ==
This command can be used to implement the same conditional processing that Blizzard's macro system uses.  It is the same API they use and so supports all the same conditionals.

Note that item links can not be part of the commands because they contain square brackets [], which get interpreted by the parser as modifiers.
