StringSplit - Add CaseSense parameter

[MrCreatoR <mscreator@…>]

This feature request is related to ​ticket #121.

To avoid a problems with splitting strings by delimiter that might have unknown letters case, the function should recieve an optional parameter $iCaseSense...

StringSplit(string, delimiters [, flags [, casesense]]])

and by default i think it should be not case sensitive, althought it will break the backward compatibility.

Example of this behaviour:

#include <Array.au3>

$aSplit = StringSplit("caBca", "abc", 1) ;Should split into 2 elements: [1] = c, [2] = a
_ArrayDisplay($aSplit)

$aSplit = StringSplit("abCde", "c", 1) ;Should split into 2 elements: [1] = ab, [2] = de
_ArrayDisplay($aSplit)

$aSplit = StringSplit("caBca", "aBc", 1) ;This one splits correctly, because aBc mathes the letters case: [1] = c, [2] = a
_ArrayDisplay($aSplit)

P.S
If this parameter will not be added, then at least the docs should be updated with the info about the fact that StringSplit is case sensitive, and i mean more than just «(case sensitive)» in the parameter description, it is hard to notice this info.

as I plan to do the comparison as in StringLower()which is not the same as other Casesense, I prefer to define the insensitivity with the flag = 4.
This flag will need to duplicate the input string which can lead memory big usage.
But for me is better than converting and comparing char by char for flag = 1.
