E2 string match functions (for LUA's string.Match functions)

see the extension tutorial. it describes all the types:

also, try 'return foobar or ""'
will return "" if foobar is nil (or false) and foobar if not.

I'm committing these now.

I think an implode and a reverse string function could be useful. I've taken the time to make them, and they work. The reverse()-function returns the string you input reversed, and the implode()-function takes an array and returns all the cells as a string. The opposite of explode.
syntax:

S:reverse()
R:implode(S) or R:implode()

e2function string string:reverse()
 return string.reverse(this)
end
 
 
e2function string array:implode(string that)
 if !this then return "" end
	Tbl = {}
 for k,v in pairs(this) do
 table.insert(Tbl,tostring(v))
 end
 return string.Implode(that,Tbl)
end
 
e2function string array:implode()
 if !this then return "" end
	Tbl = {}
 for k,v in pairs(this) do
 table.insert(Tbl,tostring(v))
 end
 return string.Implode("",Tbl)
end

we already have implode. it's named concat.
and as I told Jeremydeath before you, E2 strings are never nil, so this check in E:reverse is superfluous.

Ah, ok! Then it's no need for the implode function. Heh, I didn't even know there was such a function.
