Fixed array functions storing and comparing values as strings

[Daaisukidayo]

• $arrayIncludes parses its value, but every function writing into an array kept storing strings, so $arrayIncludes[nums;1] was false on an array built by $arrayLoad or $arrayPush, while $arrayIndexOf on the same array returned 0, and the opposite happened on $arrayPushJSON arrays.

• $arrayLoad, $arrayPush, $arrayUnshift and $arraySplice now store numbers and booleans as such, and $arrayIncludes, $arrayIndexOf and $arrayLastIndexOf parse the value they look for the same way.

• Wrapping a value in double quotes keeps it as a string, just like before.
